Bazzite is more aggressive with kernal updates and comes with a ton of gaming options and packages preconfigured. Bluefin is a designed more for productivity, but you can still game on it. It’s just not it’s main focus.
But as long as you stay within the same DE, you can rebase from one to another.

I’m no expert, but I think of it as two layers: your layer on top (where you keep things important to you) and the system layer on the bottom (what makes the computer actually run). Most people don’t care about that bottom layer, so may as well make it immutable.
Rebasing is like lifting up your top layer and pivoting it onto a new bottom layer of a similar “os”. Updating is the same thing, it just pivots to an updated version of the same os. In either case, if something goes wrong, you reboot and choose the previous version and it pivots your top layer back.
It’s been a while since I installed Bazzite but I remember it having an on boarding where you selected what you needed and it installed it for you. I skipped most of it. And I know Bluefin has a command you can run to install basic gaming programs. So you have options.
