Question about pi-hole vs adguard home vs technetium

I currently have Pi-hole and Technitium running, with Pi-hole serving as a backup in case Technitium goes down. I see a lot of people here running AdGuard Home, and I was wondering if anyone has a breakdown of the pros and cons of each service. I'm genuinely curious about this and have been wondering about it for some time. Pi-hole seems to be the original ad blocker that many of us start with when we get into self-hosting, and I'm just curious if I'm missing out on anything by sticking with my current setup.
