I've been using Ubuntu 18.04 since 2019 basically because I have so many things set up just right for what I do that I hesitate to move away from it.
But in general I prefer Ubuntu or Ubuntu-based distros.

Pop!_OS is very good though. I really think it's a good place for new people to start, but the built-in tiling & stacking window manager mode and their other desktop-management features are fun for people who come from other distros.

I've always liked Elementary OS too, have you ever given it a shot? Their apps, desktop, and App-Center full of developer apps for Elementary make it very nice. Especially for a distro that started as "Ubuntu with a MacOS theme".
