Whatsminer seems to have a pretty good reputation too. Personally I can only speak to the one unit I have had for over 2 years now.
A Whatsminer M20 running with several S17 Pros.
Almost every board of my 3 s17 pros have failed.
Whatsminer has never had a hiccup (Granted I only have had one)
I am now, within the last couple months) started running an M30S (runs hotter than the M20/S17/S19)
I also have and S19 and s19 Pro
