I do try it from time to time. My last try was with a Pixel 7 and although I loved Material You on it, my main issue was that the quality of apps wasn’t great and most just didn’t feel nice to use (even Google’s own apps feel better to use on iOS).
Didn’t help that the Pixel 7 was way too big and I couldn’t get used to that either, among a few other problems.
Meanwhile, you’ve been able to use ad blockers on Safari for iOS for years and years. Once the EU forces Apple to let developers publish actual other browsers on the App Store (and not just reskinned Safari), iOS should be pretty great in terms of browsing liberty & comfort.
