I like them all. Torrentbits.ro is one of the best Romanian tracker, with very good pretime and speed. Goem and Myspleen are good for cult - art -films. Digitalhive is a vey nice tracker, with good content. Nordic is a big Scandinavian tracker with lot of content, but pretime is not an issue there. Aside from Tb.ro they are very much "niche - trackers".
A malis vituperari laus est.
well myspleen is for cartoon shows, so unless you watch cartoons there's no point getting invited there..
torrentbits has just under 8000 torrents. Its alright, although i don;t use my acct over there, except for uploading some placeholder torrent. It looks like a general tracker..
i have never used any of the others so i cant comment on the rest.
My personal favorite is Digitalhive. It has so many freeleech packs, those really give you a hand while starting up. It has some really nice content, it's easy to seed. The IRC channel is a bit quiet, it has a bonus if you are logged in.
Myspleen has nice retro cartoons. A nice addition for cartoon lovers, some of the stuff they have is pretty of beat. They have a nice community, the forums are quite busy.
