So far I've seen ttdnsd used only in Tails, TorDNSd was seen mentioned only in the Tor mailing lists (not sure how many individuals may be using it though).
ttdnsd: kind of works, unless validation is required (ttdnsd fails as unbound forwarder, most likely because of not handling DS queries correctly)
It seems that bunch of people who experimented with DNS over Tor came to conclusion that using existing caching resolver like unbound is simpler than specialized resolvers like ttdnsd.
For the record, Tails uses a combination of the pdnsd caching DNS server, the Tor resolver (for request types it supports) and ttdnsd (fallback for other requests); details:
