I am nothing of an expert but I have done a great deal of distro hopping and have come to learn that at the end of the day they really aren't all that different.  I think a lot of it comes down to familiarity and how much you like to tinker.

My personal experience with Fedora was not a great one because SELinux gave me grief, but I am fully willing to admit it is likely user error because I am a dumb dumb.  Rather than trying to understand it or learn it or fix it, I bailed. 

I used Arch for many years.  Reports of instability and difficulty are wildly exaggerated.  It is my preferred Linux experience for command line only situations like personal servers especially.  
The AUR is a very powerful resource.   

I purchased a System76 machine last year, and have been daily driving PopOS ever since.  It just works.  I have never been a huge fan of Gnome, especially the Ubuntu brand of it, but I don't know.  I just used Pop and haven't looked back.  

All that being said, Pop is working on their own DE built from the ground up, so it remains to be seen if Pop will continue to be good, but it looks promising.  At the end of the day, it is Linux.  If you don't like your DE use a different one.  Don't let anyone tell you how to live your life.
