I don’t like to define one motor as better than another, or at least the best. Ina single batch of motors you will always have some with issues, plus there are environmental issues and usage issues, uninstall & reinstall, etc.
I will say this. I have 2 sets (x4 total) TB (@torqueboards) 190kv 6374s that have thousands of miles on them and have had zero issues. In fact I had another set that were somewhere around 6k that were so beat up they looked like the surface of the moon. I took them apart to sand and paint the cans and give them a general cleaning. When reassembling, and I still don’t know what I did wrong, I managed to trash bearings in both of them. They are currently waiting for me to tear them down again and see whats wrong.
I have a set of Maytech 200kv 6369s (@Psychotiller) and 2 sets of Maytech 190kv 6374s (1 set from @hyperion1 and 1 set from @Sender, thanks brudda’s) and they are by far the smoothest motors I’ve owned. They are precision built and I have yet to tear one up.
Lastly, I have a set of Ollin 5065 200kv motors that I have used as test motors off an on for a couple of years, but fell into the 6374 trap and thought they were big enough. I put them on my TopSpeed, all I can say is I am impressed. They are fast, dont get noticeably hot, are very quiet in FOC mode. I wish I could buy more of them.
