very usefull when you want to keep an eye on your rig while away from it, you can even restart it, overclock, undervolt, check temps, and musch more while using the free edition. Honestly, i couldn't ask of anything more (except for a few things, but they are covered by the paid version)

Minerstat works for me to use from a single station and remote office. Combined with remote access like splashtop I can cover most aspects or more than offered by other mining OS's. Can see enough under the hood to know what's going on now and have established over time some workarounds based on my rig builds. Haven't used msOS yet but intend to in the future after a farm refurb.

Minerstat gives me a good centralized management dashboard to view and control all my miners. It provides me with a good birds eye view of all my rigs in one view. It allows me to drill down and make custom configurations to one or many rigs at a time as well. There are many more features, you have to try it for yourself.
