I'd have to say Western. Realistic is always cool but not absolutely necessary. A lot of my favourite artists, like
this guy (who has posted recently! Yes! He's still around!) don't draw in a "realistic" style, but it's a style that appeals to me.
That said, content is the main concern, broad style classifications are secondary. For example, although I prefer hand-drawn art in general, I love Genyun's and Solone's stuff, mainly because they're both good artists who share my taste in smut.
As for other media, well done live action videos (ie. Missa's work) is great. I also enjoy well-written TF stories (though I'm picky; I've skipped over some stories after the first paragraph if I found the writing style grating).
