If you don't do any 3D printing, it's hard to understand the difference between bambu labs and nearly everything else.

The Bambu printers work. Imagine the difference between windows XP and OSX. Do you guys remember the insane breath of fresh air it was to get a computer which just worked?

That's Bambu. Yeah they aren't open source there's all sorts of telemetry, etc. Nobody cares because they really just want to print things.
