I honestly don’t know about much ads. I use a pretty good dns setup what already blocks most. On top AdGuard pro take cares most of the ads I would see. I use also vinegar for YouTube so I don’t see ads there haha.
On android you have with rethinkdns a pretty great firewall with a name what sounds more like a dns service. Anyway, I use apple for business, just because it works with my associates and have GrapheneOS as my daily drive.
