I've heard some inklings of that. I've heard diehard fans say that they specifically got Creality printers because they wanted to work on a 3d printer, not have one that just worked out of the box. Though the K1Max from Creality looks pretty neat.
I myself always preferred low maintenance things, but I like knowing how they work. So I got the kit for my MK4 and built it on one of my days off. Took about as long as I'd heard (8+ hours), but was worth it.
Haven't heard of sovol, I'll look into them though. Always good to know the other brands.
