Currently using a FLSUN Super racer. It’s a delta style printer and fast as hell compared to the printers I had before. 400 hours on it currently.
Had a Ender 3 before it. Lots of issues. Ended up giving it away to a friend who still uses it and still has random issues.
First printer was a Printrbot Simple Metal. Bought one the moment a heated bed was a option. Great printer for the time, but dated now. Keep thinking about resurrecting it to print flexibles on of these days.
My Ender 3 v1 build is very close to this too +/- a few things, specifically linear rails, which absolutely corrected a lot of the little issues I was having. Speed isn’t important to me, so I’ll probably keep using it for years to come.
