PowerDNS provides the standard by which other DNS resolvers are judged. It's an amazing, stable product. Our biggest features compared to PowerDNS are that we provide DNS-over-TLS, we're written in memory safe golang (which is also highly concurrent, although so is PowerDNS), and we support BGP natively, making "internet wide" deployments a breeze.
All of these things could be done with PowerDNS, but it would also require a number of other programs "helping" in order to get TLS and BGP, and the configuration would be a mess. With TentaDNS it's all in one convenient, easy to run place, with a single set of config, running multiple (even 10s or hundreds) of resolver configs all in one place.
That having been said, our Authoritative support (e.g. being the main nameserver for a domain) still lacks a lot of features, while our recursive support (e.g. being the resolver you use for your browser) is top notch.
