Did the same thing last September, my S21 Ultra’s battery was getting tired and I was tired of the Samsung bullshit. So far it’s been great and so has battery life, plus it’s a breath of fresh air to only have apps I want installed without needing ADB to remove them after Google/Samsung decides they want them reinstalled every few weeks.
Only downfalls have been my broken banking app (which might be the actual app being broken based on Google Play reviews) and the amount of tweaking I needed to do to get OSM as my default map for Android Auto.
I finally have a phone that actually feels like mine, not just a leased device from the manufacturer.
You have to use the Google Play version of OSM for Android Auto, plus tweak a setting or two in the advanced settings of AA. As for the maps itself it’s been fine, I use GPS not Google Play Services for location, so I need to make sure the phone is in clear view of the sky for best results, but it still works in the center console of my car. Just make sure your location services are on before opening OSM or it acts funky.
