You need valid torrent files. Also, some routers block bittorrent connections. Since you’re only 11, my guess is maybe your dad doesn’t want you downloading GBs of hardcore.

I’m grading on terms of project scale primarily and then on how much I use the software. I would never put Azureus above Blender. It’s only a file transfer program.
OSX isn’t OSS. Part of it is, granted, much of what makes it “OSX” is not. And most of it’s not GNU/GPL. Everything listed is. It’s often unclear what people mean when they say “open source” anymore. IMAO “open source” means anything under an OSI approved license, like BSD, GPL, LGPL, MPL and MIT. Some people just think of “open source” as “gpl.”
And “Linux” (as delivered distros are today) isn’t #1 in my book. Far from it. Too much disunion, too many soapboxes, too many high horses and too many bigots. (and for those who think I’m a bigot, I’m not: I hate all OSs equally :P)
I vote blender. Great app. Great unity. Great developers. Non-bloatware. 'nuff said.
Second is Gentoo as a tool not a distro. The term “linux” is too vague methinks. Portage is great and it makes as a whole for a very customizable experience.
The only ones I have adequate experience with are Linux and Blender. I’ve had The GIMP since October, but I get too frustrated with it to use it regularly.
