I like both, but I think I tend to like dark fantasy more.

I know, I picked the cop out option. I'm just so fickle with things like this, one minute I'm loving light art next minute it gets too sugary for me and I go into a dark art phase.
If I absolutely had to pick I'd say more of my favourites have at least a hint of darkness or edge, but I switch between phases of loving each.

^I almost picked both too. But after thinking about it I realized that most of my favourite artists are dark and the ones that aren't I tend to gravitate to their 'darker' works.

love them both

I like some darker, but prefer light
