+1 for Endeavor. Started daily driving it for about 3 months now and it's incredible.
Some of the minor tweaks I need to make really bring me back to the early days of learning PC and trouble shooting (but with actually solutions / outcomes this time and not just a brick wall at the end).
That being said nearly everything has just worked out of the box. Plus with timelapse (timeshift? I forget the name) you can basically be sure that you won't brick the system if you mess anything up.
+1 for Endeavour from me too. I came from Arch and decided Endeavour was better for me. Building your own setup in Arch is great, but so is having everything set up for me.
I actually considered this (I have a 7950X) but I recall someone on Gentoo's forums saying you shouldn't use them all even on the best liquid cooler. The heat from that would be a major issue.
Man I feel like a fraud in this thread. I've been using Linux for more than a decade now but I installed only Windows on the new system. I use it like an Xbox, turn it on when I play games and then go back to the laptop for everything else.
