Pihole, Adguard home or blocky
Hey guys, I recently bought an orange pi zero 2 and, as the title suggests, I want to put an ad blocker on it. Those are the options. I also will put openvpn for external connection to my network. Does anyone have experience with them? What would you suggest?

I've read about unbound but not knowledgeable enough to understand what it does. Could you king of eli5 it to me? Also, is wireguard better than openvpn?
AFAIK, instead of forwarding your DNS requests to an upstream DNS provider (eg. 1.1.1.1), it resolves the domain step by step. First, it asks the root nameserver “where's org.?”, the returned server is asked “where's example.org.?”, the returned server is asked “where's www.example.org.?” and so on until you get your target IP.

Edit: there is also a good explaination on https://docs.pi-hole.net/guides/dns/unbound/#what-does-this-guide-provide
Wireguard is very lightweight and it just works. No overly complex setup, tools, matching protocols, algorithms, versions, etc. It just works and it's simple UDP traffic. It's the first self hosted VPN that I actually love and that works on all my machines, mobiles, VMs with just a config file to fine tune what should go over the line.
This is the reason indeed its lightweight and installation and connecting other clients was easy with the qr code
