It's actually noticeably slower for me, but both are... not fast having to go through Grub first, since I'm dual booting.

That makes the power management issues MUCH worse in my book. Windows hibernates very reliably, so once it goes to deep sleep, even if I boot back into Linux before coming back to Windows my session is saved. Bazzite won't do that with hibernation turned off, and if sleep is broken I end up having to do a whole bunch of manual resetting on every single session, because even with Plasma's baby steps towards session saving it's nowhere close to remembering what apps you had open.

And there are the usual issues. Gaming performance is worse on most desktops with dedicated GPUs (don't believe the hype, you'll only get better performance in heavily memory-limited systems like handhelds, and definitely not with Nvidia cards). Software compatibility is still spotty and stuff breaks more often and is fiddlier to fix, as shown in this whole conversation.

So am I happy with it? There are things where it's more or less on par, and it's good to have an alternative. In practice there are still more downsides than upsides, I'd say, so it strongly depends on how actively you want to enforce change in this space.

It's... viable. Is that fair? Viable is better than whatever it was a decade ago, so... progress?
