This mirrors my experience. I've been a mostly happy Ubuntu user since 5.04/Hoary, baring a few bumps like Unity and pulse audio becoming defaults before they were polished enough for general release.

But after upgrading to 20.04, and fighting with Snap slowdowns, and yet another change in desktop direction, the weird data sharing of searches with Amazon, and weird power management problems on hardware that had previously "Just Worked", I just had had enough. I switched to Mint a month ago, and haven't look back.

I love how Ubuntu has brought Linux into the (somewhat) mainstream, but I'm just over how much it keeps changing direction, and releasing things before they're ready.
