Saying privacy is better on Android is literally insane, I can't think of a less private OS (talking about the version installed by manufacturers). Even Windows has some catching up to do to be as invasive.
For wifi, I was pleasantly surprised that I could set a custom DNS on iOS while still using DHCP for other settings. Can only set DNS on Android if I use manual IP (or just use Wireguard).
Edit: not true, Android can have custom DNS with DHCP, see below.
