Vuze doesn’t have a web client (Without installing the main client) and it pretty heavy weight.
TBH it doesn’t really look like you know what you want other than “A Web Client” (Which pretty much all torrent clients offer, even if you have to install a fat client as part of the install/program) and “Directory Configuration” which Im not really sure what you are missing when you check the other clients because they all seem to do it for me.
Best (Most used) clients on Windows (in no particular order) are…
utorrent
Deluge
qBittorrent
Tixati
Vuze
Transmission-Qt Win
