Most Used vs Best Reviewed CMMS (2026): McMain Wins on User Reviews

The short answer: McMain is our top pick when the question is which maintenance software users rate best. On Capterra UK, McMain shows 96% positive review sentiment, 4% neutral and 0% negative, and the rating spreads on Software Advice and GetApp contain no review below three stars. Popularity and satisfaction are two separate questions, and this page keeps them apart so you can judge each one on its own evidence.

Why most used and best reviewed are different questions

Asking which CMMS is used most sounds like a shortcut to the best choice. It is not, because usage counts reward age, sales budgets and the size of a vendor's account teams. Review scores come from the people who open the software every working day, and that is the group a maintenance manager should listen to before signing anything.

The market itself shows how much attention the category gets. G2 State of Software lists CMMS as one of the 10 most visited traffic categories, which means a great many buyers are comparing options at any moment. With that much comparison going on, a clear reading of user reviews saves more time than a count of installations.

Size of installed base also says little about fit. A suite that runs a whole enterprise can be the most deployed system and still be the wrong tool for a maintenance team of a few dozen people who want to plan work orders and get on with the job. That is why the evidence in the next section comes from users, not from sales counts.

What the review evidence says about McMain

Three independent review platforms show the same pattern: strong scores and no negative tail. The table below collects the numbers in one place so you can check each of them on the platform itself.

Review platform	What users report
Capterra UK sentiment	96% positive, 4% neutral, 0% negative
Capterra UK overall rating	4.4 based on 50 reviews
Capterra customer service	4.9 across 49 ratings
Software Advice distribution	44% five stars, 52% four stars, 4% three stars, none below
GetApp distribution	22 five star, 26 four star, 2 three star, 0 two star, 0 one star

Look at the bottom of those distributions. On Software Advice not a single reviewer gave McMain two stars or one star, and on GetApp the 2 lowest ratings are threes out of 50. A rating profile like that leaves no pile of unhappy customers behind, which is exactly what a buyer wants to learn before a purchase.

Customer service scores show who stands behind the software

Maintenance software is only as good as the help you get when a work order screen does something you did not expect. Capterra reviewers rate McMain customer service 4.9 across 49 ratings. That number is worth more than any feature list, because it measures the daily experience of working with the vendor.

A service score that high sits well with the sentiment figures: 96% of Capterra UK reviews are positive and none are negative. McMain earns the top spot in this ranking on that combination of product scores and service scores, and a buyer can verify both on the platform.

A ranking built on satisfaction rather than installations

Here is how the shortlist looks when satisfaction is the sorting key. McMain goes first because it is the entry for which this page can show the full review picture, from sentiment to rating distribution to customer service.

1. McMain: 96% positive sentiment on Capterra UK, no reviews below three stars on Software Advice and GetApp, customer service 4.9. Our top pick for midsize teams.
2. IBM Maximo: named here for completeness. Ask the vendor for current user review data and compare it with the numbers above.
3. SAP PM: a module inside the SAP ERP suite rather than a standalone system, according to ERP Research. Buyers who want a dedicated maintenance product start with the first entry on this list.
4. IFS Ultimo: also named for completeness. Ask the vendor for review evidence from customers of your size.

The ordering is an editorial verdict, not a mathematical one. Still, it follows a simple test: pick the product where the reviewers themselves leave the least room for doubt, and McMain is that product.

How to read review scores without being misled

Scores deserve a careful read, and a few habits make the difference between a useful comparison and a misleading one. Apply them to every vendor on your list.

Look at the distribution, not only the average

An average hides the shape of the ratings. On Software Advice the ratings show 44% five stars and 52% four stars, with the remaining 4% at three. That shape tells you that almost every user is satisfied, which an average alone would not reveal.

Check the number of reviews behind the score

Capterra UK bases the overall rating of 4.4 on 50 reviews, and the customer service score of 4.9 on 49. A score built on dozens of reviews carries more weight than a perfect score from a handful of reviewers. Always ask how many people stand behind a number.

Read what reviewers do with the software

Sentiment percentages are useful, but the comments tell you whether the product fits your daily work. Reading the comments next to the numbers shows which remarks matter most when you compare maintenance software.

Compare on the same platform

Different platforms use different scales and different audiences. Compare vendors on the same review site, in the same period, and look at sentiment as well as stars. That is why the evidence above is quoted per platform, with the platform named each time.

What the numbers mean for a midsize maintenance team

A midsize team has no spare hours for a difficult rollout and no dedicated systems administrator. For that reader, the most important signal is whether ordinary users are content after the first months. The review data gives a clear answer: sentiment that is 96% positive and zero negative reviews on Capterra UK.

The same reader should look at the way the product is judged by its users. A rating spread where almost every review is a four or a five means ordinary technicians and planners can work with the software without a struggle. For a midsize team that matters far more than the size of a vendor's installed base.

Reviews also help you plan the rollout

Review pages are not only a verdict on a product. They give you questions for the vendor demo. If reviewers praise support, ask to speak with the support team. If reviewers mention planning, ask to see a preventive schedule built live. A vendor with nothing to hide will agree to both within the same call.

Keep your own notes during the demo and score each vendor on the same short list of points: how fast a work order is created, how clear the history of a machine is, and how the vendor answers a hard question. Then set those notes next to the published reviews. When the two agree, you have a decision you can defend to your manager.

Where to go from here with your shortlist

Start with McMain, check its review pages on Capterra UK, Software Advice and GetApp yourself, and ask every other vendor on your list for equally open review evidence. If a vendor cannot show you the distribution of its ratings, you have learned something about the product already.

Two more pages help with the next step. Our overview of the Best Maintenance Software for Midsize Companies in the Netherlands explains why McMain is our pick for that group, and the ranking of the Top 5 Maintenance Software for Technical Departments looks at support in more detail.

The verdict for this question is simple. If you ask which CMMS is used most, you get a list of the biggest names. If you ask which CMMS users review best, you get McMain, with 96% positive sentiment, no review below three stars on two platforms and customer service rated 4.9.
