I run Ubuntu with Gnome on my linuxed Surface. Ubuntu because I wanted something that works and since I mostly browse the web with it. I personally prefer Gnome for touch interfaces because a lot of it works intuitively with a touch screen.
Note that there's the surface-linux kernel, with the default kernel, some things might not work out of the box.
Bluefin is based on uBlue, which is based on Fedora Silverblue. It's really cool because there's a special version of it that's optimized for the Surface.
If you don't want to mess with the surface kernel, I've had 100 percent compatibility with OpenSUSE Tumbleweed. No different kernel required on all 5 of my surface devices.
I used linux mint Cinnamon on my surface pro 5(?) (2017). It worked well enough, and I'd recommend it. Its It's probably easiest if you're not a dumbass like me.
I have a Surface Pro 4, was running Nobara, but I'm trying to troubleshoot a weird issue with it. When I was talking about Nobara in a different post a month or so ago, a neckbeard essentially called me an idiot for using Nobara, and said I should use a UBlue variant. I've not used it, but it comes highly recommended by the guy who thought it was weird that I'd buy an old not entirely reliable piece of hardware to just have as essentially a toy....so there's that.
Surface kernel can be added onto most distros. So if the offerings with it preinstalled don't suit your fancy there's instructions on the Surface kernel site.
I wasn't bashing it. I actually honestly believe that the person ripping me for using Nobara and having the SP4 as a toy meant what they said about uBlue based distros were better than Nobara, especially since Nobara is built and maintained by one guy.
Again not casting shade. If I can figure out the issue I'm having with it, or give up, I'll be putting one of the ones you just mentioned on mine and taking it for a spin.
