ToG and FT are currently my favorites, followed closely by One Piece (and thats only because i havent really enjoyed punk hazard stuff much) naruto and bleach i sorta follow 'just because' since they release the same time as OP. But ToG seems like a much fresher TYPE of story as opposed to the normal japanese structure of story. FT I enjoy simply because its done well- but still really suffers from the common problems as most Japanese mangas..
What I'm really getting at though is if you're on the fence about trying ToG, giving it a chance is definitely worth it, give it a few chapters and see how it works for you. Highly recommended if everyone else's opinions on ToG weren't enough to make it clear.)
Berserk I like, but the time between releases kind of turns me off... its fun when updates actually happen but I just don't think much about it anymore.
Vinland Saga hasn't been too bad either, its also a bit slow on the releases it seems, and the story has slowed down a bit as of late (imo) but was a decent read.
Also been reading Ubel blatt a bit - its got some bad and some awesome to it, but seems like it hasnt had much of a following/isn't overly popular. This one supposedly started up again after a horribly long hiatus... but I haven't seen much more than a few updates so who knows wtf is going on with its author. Still a fairly awesome read if you like some action with some titties thrown in here and there /shrug
