What DE are you using? Some of the higher profile ones (Gnome, KDE) try to be all smooth and polished and feature-full and in my opinion just introduce more complications and bugs that get in the way of just being a good desktop. I like XFCE because it's just a really good, simple window manager, desktop, and set of basic utilities. Other than that it just gets out of your way and doesn't make you relearn how to do things every few years. It's like if the Win98 desktop got another 30 years of gentle refinement.
I’ve tried XFCE, i3, Pop Shell and plain Gnome.
But it doesn’t really matter, since the DE doesn’t determine how individual apps behave.
My baseline is OSX from decade ago OSX with native apps where everyone was following the Apple HIG so consistently that using a Java app felt like waking up in the twilight zone. macOS these days have fallen quite a bit from its UX glory days but there’s still quite a bit to go before it hits the level of Ubuntu or Windows.
On Linux it feels to me like every app exists in its own parallell dimension where you never know if even the basic laws of physics still apply.
