I started with Creality K1C and I am generally happy - prints all the fancy filaments like PA6CF with no issues. It's an enclosed coreXY printer with an extraction fan so I can vent all the fumes through the window. Runs open source firmware that can be modified by user. If I wasn't limited by space, I would get a K1 Max. It needed some upgrades - most of them you can 3D print.
If I had more money to spend, I would definitely go with Prusa Core - for the ideological reasons mostly.
I actually don't hate it. I like that it's not aggressive looking like every other car on the market. And I absolutely dig the interior. I would have hated it in a sports car, but it works great in Luce.
