My old work ran 6 FFF machines, the only one that seemed to have 100% uptime was the Prusa. Mind you this was several years ago, before Bambu hit it big. But we had several machines with autoswap beds etc, fancy stuff.

After that experience I got a Prusa, I'm only an occasional printer but I've put maybe 5 rolls of material through it over the course of a couple years and haven't had any stop+fix issues.
