FlorisBoard with the Material theme.
Tried many, but FlorisBoard’s bugs bug me the least, not that there are many. The one feature I wanted was password manager autofill bar, FlorisBoard worked the best at the time and has been solid since. Material theme is nice too.
Another vote for Aurora.
Universal Blue in general has been really solid, I remember one time in the last year or two when there’s been any need for manual intervention. And that came with a notification after boot, with a link to instructions that were all copy-pastable as-is to the terminal.
There’s occasionally something buggy, but the last time I ran Windows there were a lot of bugs too. They’re just abstracted away, which Linux DEs don’t do at all.
For me, it’s about choosing the bugs that bug me less. If Windows is working better for you, just run Windows. Internet points are not worth much.
I’m not sure if this is of any help, but I had the same issue with Wake on LAN enabled. This was a while ago with an Asus motherboard.
If you don’t need WoL, disable it and it should fix it if your MB is affected.
But if you do need WoL, look at https://wiki.archlinux.org/title/Wake-on-LAN.
The section 5.2.2 Fix by kernel quirks was what fixed it for me.
