I've just recently switched from a Galaxy S10 to a Pixel 7 as I wanted to see the "vanilla" experience, as well as be closer to upstream for software updates. My S10 still works great, though the battery needs replacement (at the time, it had already broken the glue on the back glass and was still expanding -- didn't realize until I took it out of the case for cleaning)...
With my S10, I had to really fight to get it to let me use Google's apps over the Samsung ones; which whole annoying is doable. So far, the only things I really miss from Samsung (and notably the UX):
- The sidebar/panel with an additional set of predefined apps
- Replaced with Panels
- The volume/silent switch in the notification shade
- The Bixby button (for custom actions)
- Physically smaller phone, but that's not a huge deal
Overall, I'm happy with the experience so far; though I dunno if the "Pro" model of anything is really worth it.
