Hello, this may be a little annoying and may be a tad biased to ask here but I am genuinely curious of the benefits of one vs the other. As far as i can currently see the main benefit is a built in recursive server functionality which I am currently solving with unbound. Pihole is obviously much more popular as well. Are there any other major benefits of one platform vs the other? Thank you for you thoughts on the subject. Sorry if its not the best idea to ask this on a pihole forum.
The only real way to know is to use both and pick the one that solves your particular needs.
Not exactly the answer I was hoping for but you arent wrong... Well i guess its time to install technitium and try it out. If i cant decide i may just use both. One as a backup. One thing that I notice immediately is that technitium doesnt have an official docker container. There is an unofficial one though. I dont use docker but when i eventually build up my home network that is the plan.
Your going to be the expert on this matter if your the first to try out both 
Ok well... I tried setting up technitium last night. All went well... Its a little more complicated because it functions as a proper authoritative server and uses zones. While setting up i was trying on one machine... When i finally tried to update the router settings so i could try it on the network... I may or may not have almost bricked the router... So I had to reset that and stuff... To be clear it didnt break because of technitium it just broke. So i uninstalled technitium and just stuck to my comfort zone. Technitium was actually kinda nice while it was running. I would recommend it especially if you want unbound style recursive functionality built in.
I ran into the same problem.... wanted pi-hole to block stuff on my network and then found technitium.
I've been running them both as docker containers for about a year now.
Technitium is the main DNS server (unblocked) for IoT, work equipment etc and pi-hole sits before it covering the rest of the network.
My problem with it is that my logs are scattered over pi-hole and technitium.
Technitium has blocking features as well, so I'm about to cut out the pi-hole completely and just use technitium for everything. It's quite capable, solid and stable.
That being said, if you're not comfortable with DNS, I still think pihole is the better option because it doesn't throw every possible DNS feature at you. There's a lot less to mess up. If you're looking for a DNS infrastructure with more capabilities, I'd say just leave out pi-hole completely and keep your infrastructure as simple as possible.
