Like I said, the printer is decent, or even quite good. I still prefer my Prusa, but it's largely personal preference. I'll go a bit into the nitty gritty on this.
I dislike the slicer and how it's basically a Prusa Slicer clone but even more unintuitive. The printer also heavily relies on QR codes for troubleshooting. I also don't like how it pushes you to make an online account to print GCODE, and I don't like using MicroSD cards to print if I choose the go that route. The "lidar" sensor (it's not really lidar) feels like a gimmick, and the lack of a PEI sheet is borderline unacceptable to me. Going back to glue stick feels like I time traveled to 2017. The default startup process for each print takes forever and requires adjustment in the Start GCODE or EVERY print starts with resonance compensation, flow calibration and 1st layer check. I personally would've gone with the P1 series which side steps a few of these issues, but that sadly wasn't my call... Even though I end up being the guy that maintains the printer in my firm >.>'
The speed is nice, but my personal experiences shows that it has a noticeable effect on surface detail and finish and has a substantial effect on layer adhesion/strength. The speed also makes the printer very loud. Easily the noisiest one I work with. I'm sure I can tune most of not all of those issues out since the majority of printing quality is derived from slicer settings nowadays, but I won't be spending that time and effort to do so, especially on a printer that isn't mine. I may seem picky about this, but I print 1/16th and 1/8th inch scale architectural models, and the surface finish is my #1 concern, so this might just be a me-specific issue.
The AMS is nice when it works, but if filament snaps, especially in the internal PTFE hub connector, it's an annoying process to take the entire thing apart and hunt down the problem in comparison to the MMU2S. I've seen some nightmares regarding the rewinding mechanism online, but I haven't experienced them myself, so I like that a lot so far. Much better than the annoying spring-based spool holder + Repbox setup that I use with my MMU2S.
I'm undecided on the hotend setup so far. It seems reasonably reliable, but I haven't had the need to take it apart yet, so I don't have an opinion on it until that day comes.
