I have and Ender 3 Pro I have done the :"Replacing the nozzle and clearing filament jams are pretty easy."

With my Bambu for 18 months, problem just doesn't exist. I have spare parts because previous experience said I'd need it. But not yet.

The most egregious operational issue is the occasional hairball, even then, the printer often catches the issue and pauses the print to let me check on it - automatic hairball detection.

I don't like the Bambu company and I wouldn't buy one now thanks to their lock in practices. My Bambu won't get the "fuck you" firmware update.

But as to their hardware reliability for "just printing stuff" - it's pretty awesome. If other companies have caught up to this, then the 3D printing world is in a much better place.
