I install qBittorrent about once every six months, then uninstall it again because it just doesn't do what I want it to do (specifically in terms of the interface and its handling of RSS feeds). I actually kept it installed for a while before what.cd died, specifically because it was whitelisted there.
May I ask what you feel is missing? It got an RSS feed reader, you can set up automatic download filters - simple and regex, pick what feeds each rule applies to, you can set quite a few other options for your RSS downloads than your regular downloads. I see it doesn't really have a smart filter to prevent multiple versions of the same episode from getting downloaded, but usually I just amend the filter until there's only one version in practice.
