BTN and PTP are not overrated for sure!! BTN has the best, the biggest and largest number of TV series and episodes. Freshon, BitmeTV and others in the same category are not even close! Same with PTP apart from HDBits and CHBits it is the biggest movie tracker. with a very nice interface and community.

Some other old trackers are a bit overrated nowadays.. like BitmeTv, SCC, Bitme.. just because they are old and lack fresh blood
