It is a pity that many private trackers are not going with the times
Tixati, Transmission, Deluge, qBittorrrent -- there are definitely better programs than μTorrent out there, helas -- most private tracker administrators are too lazy to adapt to them. The deadbeat 'argument' is usually that the new BT clients tend to report upload volume/ratio «wrong» -- as if seeding capacity was in any short supply on private trackers, quite the opposite: seeding/ratio requirements do not foster but hinder the interchange of data these days, because there is such an enormous over-capacity on the supply (seeding) side that most cries for help in the forum are usually 'help, too many seeders, my ratio is in jeopardy'. Still, the dance around the golden calf of ratio is the pretext why modern features and techniques are not implemented on the tracker sites, which often ban the best BT clients from being used.
Unfortunately, there is a lack of cooperation in order to enhance the BT protocol itself. One of the biggest annoyances is that torrents of the same content but with different hashes are not being combined intelligently. We all know of cases where the .iso and .nfo files in a torrent are the same, but the vanity of forum/tracker administrators drives them to include a stupid «downloaded from nitwit.com» text file that results in a different hash. There are even intelligent ways to combine the otherwise identical torrents nevertheless, even without improving the BT protocol, but since too many tracker administrators force their members to stick with μTorrent, μTorrent's programmers couldn't care less and rather concentrate on new ways of ramming advertisements down our throats.
Resistance to change, the age-old problem of mankind is the highest hurdle that new, better and more convenient BT clients with more efficient advanced features (and friendlier staff or customer service) have to overcome. Until tracker administrators do not open up to them, people will be forced to stick with the dinosaurs of the past, despite the lousy attitude of their makers, especially those of μTorrent.
