There are more BitTorrent clients than we could possibly compare, but some of the most popular -- and best -- have been under the spotlight lately for sleazy ads and bad behaviour. It's time to check in on a few of our favourites to see how they fare, which deserves your downloads and which ones you can trust.

iOS: Previously mentioned Transmission already has a pretty nice remote, mobile-friendly web interface, but if you're looking for a native app experience to monitor your torrents, iControlBits for the iPhone will do it with speed and style.

Popular Windows BitTorrent client uTorrent just released its first stable 1.0 client for Mac yesterday, but most users are sceptical about leaving Mac favourite Transmission (which recently reached the 2.0 milestone). Here's how the two stack up against one another.

Mac/Linux: The very popular open source BitTorrent client Transmission has reached another milestone, and while it's big January update added some great features, this release is all about speed and stability.

Mac OS X/Linux only: The popular BitTorrent application Transmission updated to version 1.70 a couple of days ago, then quickly released 1.71 today.

Mac OS X/Linux only: Popular BitTorrent application Transmission has updated with several excellent new features, including built-in integration with the Clutch web interface. We showed you how to remote control your BitTorrent downloads with Clutch from any web browser, and now that Clutch comes baked-in to Transmission, doing so is even easier (though you may want to refer to the original guide for the finer points of setting it up). The new release also includes integration for Quick Look in Leopard (just hit the spacebar) along with several other improvements. Transmission is free, Mac OS X and Linux only. Tramission
