Good discussion here.
For anime, I've not dived in too deep, but I'm a big fan of Stein's Gate, and my guilty pleasure is Girls und Panzer.
For manga, I'm new to this as well, one of my favs is the original Devilman, though I admit it packs some really hard hits towards the end.
For comics, it's another discussion. I prefer to follow writers, and some characters. Too many underrated gems in the genre.
