What other good torrent clients are there out there aside from uTorrent? New versions suck and I kinda don't want to resort to an older version, unless they're still the best torrent clients available.
i'll again recommend deluge (BIG recommendation). if i knew how to move torrent statistics from one client to another, i'd be using deluge at this very moment, but idk how to import the stats from utorrent and i have yet to find out. EDIT: oh and it's worth mentioning that because utorrent is closed source, nobody knows how it writes the formats for its stats and resume files. so importing them to another client will pretty much always be a crapshoot. you could try to reverse engineer them, but that's just such a terrible terrible thing to force upon a human being
vuze exists, but it's one of the heaviest clients out there and it always has been; moreover it's built in java so it requires and has all the problems of the java virtual machine. if you're more interested in lightweight clients, this is not the one to be looking at
if you wanna do it the classy way, there's rtorrent, which is a command-line front end for the well known libtorrent library (upon which many open-source clients are based). i think it's unix only? there's a ton of style points for anything that's command line only in my books (props to umbreon dan for bringing up mutt, which is a command-line email client and one of the most powerful email clients that exists right now), but your mileage will probably vary lol
then there's q bittorrent which is heavily inspired by utorrent. it's basically utorrent, but written in qt so that it's cross platform off a single build. i don't think it has the force of mass to adopt all the random bs that's cropped up in more recent utorrent builds; in other words it's inspired by OLD utorrent (a good thing >_>)
and if you're on mac, transmission appears to be one of the dominant clients for that platform, by a pretty solid shot from what i know. i wouldn't consider it a big contender on windows though, and although transmission runs on linux systems, i don't think you're too likely to see it. most linux systems would probably be using rtorrent, deluge, ktorrent, etc that are developed primarily for a linux user base; transmission has always given off a mac feel imo.
you can probably find a lot of outliers, but i've focused on the big ones because they're the ones that have the most private tracker support. as i mentioned earlier, most private trackers use a client whitelist. this is because there are a lot of bittorrent clients that violate the bittorrent protocol. they lie to the server about how much data is being moved, they promote leech-heavy or hit-and-run tactics that damage the health of the torrent swarm, etc. private trackers take a lot of pride in the quality of the swarms they maintain so they in general do not take kindly to such bs. rather than find out which ones to block and allowing all others, it's easier to just pick a small pool of trusted ones and block everything else, seeing as a select few clients (utorrent, vuze, transmission) probably make up like 75% of the user base. thus you might find that a more niche client wouldn't be allowed on a private tracker, which is a strong argument in favor of using a popular client. (also note that if a client has the ability to change its user agent - the thing that lets a server identify what client it is - it'll almost instantly be blacklisted for circumventing the whitelist controls >_> not many clients actually do that in their release builds though.)
