1. The Pirate Bay
The Pirate Bay is probably the best known BitTorrent brand on the Internet. The site was founded in 2003 and is still expanding, despite the various legal troubles and blockades that were designed to hurt the site in recent years. The Pirate Bay currently has close to 2 billion page views a month.2. Torrentz
Torrentz has been the leading BitTorrent meta-search engine for years. Unlike the other sites featured in the list Torrentz does not host any torrent files, it merely redirects visitors to other places on the web.3. KickassTorrents
Founded in 2009, KickassTorrents is one of the youngest sites in the list, and this year it moved up to the top 3. Responding to the increasing worries about domain seizures, the site moved from its kickasstorrents.com domain to kat.ph a few months ago. The site continues to innovate and release new features every other week.4. IsoHunt
In 2010 isoHunt became the first search engine forced to implement a keyword filter provided by the MPAA. Despite this setback, isoHunt continues to be listed among the top torrent sites. In 2012, isoHunt hopes to get rid of the filter through the Appeals Court.5. BTjunkie
BTjunkie had to deal with a setback a few months ago when the site was blocked in Italy following a court order. In response to the block, the site’s owners launched an ad-free proxy site for Italians only. Just as last year, BTjunkie settles in fifth place.6. ExtraTorrent
ExtraTorrent is one of those robust torrent indexes that doesn’t make the news very often. Compared to last year the site has moved up a spot and is now the 6th most popular torrent venue.7. Demonoid
The semi-private tracker continues to attract a massive audience, also on the new .me domain name. Behind the scenes the site’s owners are working on a new and improved look.8. EZTV
Unlike the other sites in the top 10, TV-torrent distribution group EZTV is a niche site specializing in TV content only. Despite its fair share of downtime this year, EZTV has managed to get a spot in the top 10 for the first time in its six year existence.9. Bitsnoop
BitSnoop is another newcomer that gained a large audience this year. This didn’t go unnoticed by the RIAA, who filed a complaint at the U.S. District Court of Columbia and obtained a subpoena to reveal the identity of BitSnoop’s owner a few months ago.10. 1337x
1337x is also new to the top 10, and focuses more on the community aspect than some competitors. The site’s owners say they started 1337x to “fill an apparent void where it seemed there was a lack of quality conscience ad free torrent sites with public trackers.” Its 10th place this year proves that they’re getting the success formula right.I have checked all above sites to download different softwares and videos with different torrent softwares, so with my opinion the best site is first one "The Pirate Bay".
