Pop!_OS. I have always loved System76 and have one of their laptops, as well as an HP Dev One that I use as a daily driver. The convenience and tiling system of the distro is the simplest I've used so far and works perfectly. I used to run Arch but I just don't want to deal with it anymore, honestly.
I've got pop running on my thinkpad, been upgrading for a few years now. It's getting a little crufty, but no real problems in all that time. Hard to make an argument to change. If it ain't broke...
