Oh, I'll have to agree, D-Gray man was pretty good~
I don't quite have one deninitive favorite, so I'll just choose a few that I liked:
Fullmetal Alchemist (Brotherhood): That was the first anime that I watched online with fansubs. I watched both versions, the newer one first, and I do actually prefer the new version, though I have to say that the older one wasn't too bad either. The newer version has a tiny bit of romance, nearly non-existent, though I have to admit it still annoyed me The older one didn't have any romance at all, if I remember correctly, and I liked both movies as well~
HunterxHunter (2011): Another long shounen/action series, really good, I enjoyed the friendship between the main characters. I didn't quite like the ending, but one of the later arcs (Chimera ant arc) was awesome. Overall it was really fun to watch, with no romance at all~
Log Horizon: If you want to see an anime about prople trapped in an video game world, this is the way to go. Instead of taking the route of characters trying to get back to this world, it tells the tale of how they try to live in that world. It really seems to understand it's otaku characters and the "game" as well. Very well done. A little bit of romance, not too annoying though~
(The names are links to their mal pages with summaries etc.~)
I could go on about this forever, but I'll keep it at this for now~
