NextDNS

Very good, sometimes too good at blocking shady hosts. My amazon mobile app crashes all the time when nextdns is on.

It's great as an extra level of blocking on top of uBlock, and it works everywhere on my Mac rather than just within my browser. I also love the Analytics page, it's really cool being able to see what goes on behind the scenes, where my laptop is connecting to, and how often.

Set up with my router to stop ads

block unwanted queries at the DNS level - around 10% of all queries in my case

Simple but awesome controls over trackers.

It’s allowed all my devices to have ad blocking across all apps. iAds no more!

Like a cloud-hosted Pi-hole - you can control how your network blocks ads, trackers, malware, and known phishing domains, as well as manually control whitelists/blacklists, redirects and so on. There's also an iOS app to use as VPN for LTE connections.
