I flip between the two when I get bored.
Mostly use google services on the iPhone currently. Don’t really ever use the apple versions like photos, safari, maps etc
As others have said there’s not a huge difference nowadays. Home screen layout is the main one, and third party accessories.
Android I prefer for some things but my entire family/friend group being iPhone has it’s advantages too
I do wish you could swipe back from the right hand side rather than the left on iPhone but that’s my main gripe
