Pop!_OS by far.
Note that NVIDIA ships proprietary, out of tree drivers.
No Linux Distro really supports NVIDIA as they cannot fix the drivers, as they are proprietary.
Manjaro is weird semi-rolling with a criticised mechanism of holding back packages without real testing (which might be outdated info).
PopOS is based off Ubuntu LTS, a stable distro and the most common Linux variant.
Stable distros will not break the NVIDIA stuff. NVIDIA doesnt care about rolling release etc, and Distros need to not break it, as they can package them but not fix them.
Yes, Bazzite using Fedora Atomic is very nice through the inherent stability of the OS distribution model.
But they rely on rpmfusion, an external repo packaging the proprietary NVIDIA stuff for Fedora. The repo is not supported by Fedora, and the drivers cannot be fixed by anyone.
Keep that in mind. NVIDIA sucks.
