I mean, you use Linux with Nvidia, some trouble is basically guaranteed. I've heard it has gotten better, but there used to be tons of problems and now there are just fewer tons.
As for quality Desktop experiences: There are a lot, but Kubuntu I've also tried and found to be a buggy mess and Manjaro is kinda controversial in the Arch bubble - because it's an attempt to make Arch less Arch (and buggy as well).
I'll just list some distros you might want to try:
Endeavor OS
Basically preconfigured, but quite vanilla Arch
Garuda OS
Depending on your choice of ISO, more or less heavily customized Arch
Providing useful tools as well as fallback options in case some update goes wrong
Depending on the ISO quite lightweight, but might be gamery themed
Sparky Linux
Choice between Debian Testing and Stable for more or less frequent updates
Debian, but more friendly toward new users
simple, lightweight
Peppermint OS
Debian based
Actually good looking XFCE
Unique selling point: Open websites respectively web apps in dedicated browser instances, linked on the desktop like regular apps
openSUSE
A classic; Standalone with the chocie between a rolling and a versioned release
Maybe a bit more stable rolling than Arch
Solid support by corporate software, less community support than on Arch (due to the community being smaller)
