In a word - yes. I have the X1C, not the P1P, and previously had a FFCP. I don’t have much direct experience with other printers to compare. The X1C has been an amazing, frustration free experience so far. No more hacking together gcode or having to tweak it, no more manual bed leveling, no more dealing with octoprint, and multi color prints that actually work (via AMS). It’s literally been a turn it on and print experience. While BambuLab isn’t perfect, it’s a massive step up from the 10 year old FFCP for me.

Removing and re-adding my account in Liftoff world for me too.

I use the spray cans, and it just takes some practice. If the result isn’t good you can wipe it off and try again. It’s not an easy skill to master at all.

I use Manjaro, but I run it like vanilla Arch (for example pacman/yay and not pamac). I find this to be a sweet spot for me - rolling releases are so incredibly nice, and Manjaro being slightly slower than Arch is good from a stability standpoint in my experience.

I use ZFS all over the place, including the root storage pool on my home server, which has overall been a great experience with systemd-boot.
