I see your point… I use Debian for my self-hosted environment, so having similar system on desktop may save some cognitive load. My main arguments against Debian are (maybe misinformed though):
No btrfs support in installer OK, Debian wiki says it’s there
Major annual upgrades to keep up with stable look more scary than more incremental and frequent updates of Fedora. And using Sid as someone suggested sounds too crazy for main PC
So yeah, looks like it’s just upgrades… Gives me something to think about while I’m moving my apps to flatpaks
