Eh I have a hard time picking one. I like stuff that just sounds good to me, whether it's SA, Dark Psy, Prog, Suomi or Full-on.
I would like to vote for Full-on, because when someone makes very good melodic full-on, it's hard not to love the genre, but in the end, if I take a look at a handful of Full-on, there's just so much boring and unimaginative shit in there...
