I have a Voron 2.4 right now, and had a Prusa MK3 before that.
It remains to be seen what additional work the kit amounts to. The Prusa XL can be assembled within a few hours while the Prusa MK3 is a day project and the Voron is a multi day project, not even including the time needed to research the different Voron kits.
Assuming it does not lack in features or quality, I think the price for the kit is fair since it includes the full Prusa support, next day shipping for replacement parts and it is made in the EU. The Voron with its flying gantry is dope, but I do sometimes miss being able to just write Prusa about an issue and get replacement parts under warranty in 2-3 days.
btrfs has been the default file system for Fedora Workstation since Fedora 33 so not much reason to not use it.
