Easy and efficient
Minerstat is really easy to use (configuring the actual miner can be complicated though). I switched from using the desktop version to the minerstat OS and it has worked flawlessly after properly configured. Any instability I had in windows is just gone as well, and getting more hashrate and efficiency out of my system now.
With Minerstat, I barely need to access my rigs again. I can control everything I ever need on my mining journey. Excellent knowledge base and support too.
Single station and intuitive
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.
