Adguard Pro vs NextDNS? What is best for blocking ads, trackers, and encrypting DNS? Are one of these alone good enough?

I'm trying to keep my iPhone as privacy focused as possible. Yes... I know that android devices can be locked down more than iOS devices but I don't need it to be the most private device ever. I just want to do what I can and block trackers, ads and encrypt my DNS traffic.

I have Adguard Pro, I have not tried NextDNS. But I don't want to have a subscription fee if possible.

Are either of these apps good enough to keep my device as private as it can be or is there more I need to do? Which app would you use or recommend for this?
