Flatpaks have finally made most distros interchangeable for me, they’re a wonderful tool. Not every single thing should be installed with them, but the current compromise of shipping core system components (including DEs in here) as native packages and user apps as flatpaks has drastically reduced the amount of troubleshooting I’ve had to do. When the vast majority of your tiny packages have no overhead, you can eat a few gigs for a nicer user experience. Even on my 120GB laptop that hasn’t been a practical issue for me.
