Depends on how comfortable youd be with voiding the warranty. There’s a replacement firmware available for the X1C line, and there’s a board replacement for the P1 series that allows you to run klipper instead of the Bambu firmware. Fwiw, I couldn’t care less (at least for now) about having to run their slicer, its good enough, for Arch based distros you can install from the AUR and for others, at least Debian/ variants there are flatpacks

Also something to consider, the average size of what you’ll be printing. Yes, you can make things in multiple pieces, however if youre constantly printing parts that dont fit the “standard” ~250mm cube you may want to look at the larger format printers
