I've been using Kubuntu for years with good results. I prefer KDE to Gnome, which Kubuntu takes care of, and I normally add in the flatpak repositories so I don't need snap. That has generally worked well for me in the last 5 years.

For certain timeperiods I have needed to switch to Fedora, or the Fedora KDE spin, to get access to more recent software if I'm using newer hardware. That has generally also been pretty stable but the constant stream of updates and short OS life are not really what I'm looking for in a desktop experience.

There are three issues that linux still has, which are across the board:

- Lack of commercial mechanical engineering software support (CAD & CAE software)

- Inability to reliably suspend or sleep for laptops

- Worse battery life on laptops

If you are using a desktop and don't care about CAD or CAE software I think it's probably a better experience overall than windows. Laptops are still more for advanced users imho but if you go with something that has good linux support from the factory (Dell XPS 13, Framework, etc.) it will be mostly frictionless. It just sucks on that one day where you install an update, close the laptop lid, put it in your backpack, and find it absolutely cooking and near 0% when you take it out.

I also have never found something that gave me the battery life I wanted with linux. I used two XPS 13's and they were the closest but still were only like 75% of what I would like. My current Framework 16 is like 50% of what I would like. That is with always going for a 1080p display but using a VPN which doesn't help battery life.
