Even putting the OS aside I believe some of the jank is caused by Ubuntu's insistence on trying to usurp applications installed via apt to instead install them via snap. This is why my Firefox install wont allow me to copy text at random, and why I can't drag and drop files into Telegram, and why every file I download has to be dug up from some deep .snap/ directory before any other application can actually load it.
I did vow to migrate to Debian eventually. It never completely happened, as my Lenovo went to Fedora and I eventually decided to eliminate Linux entirely from my home network. But nowadays, Debian is totally mature and able to tackle modern hardware much better than it could in 2004, and I believe that this is attributable to a lot of packaging and integration work by Canonical.
