Personally I like dramas better as more of my favorite movies are dramas. Horror is very popular in the indie market. At the festivals I have been too, almost all the entries were horror, and I don't think there was one drama. However, I find that the horrors have weaker scripts, weaker acting a lot, and the plots just don't hold together as well as a lot of dramas.
V/H/S for example was hugely popular, and I thought it was one of the worst movies I have ever seen, mostly cause the plot does not hold together. I understand how you have to suspend your logic sometimes but a lot of horror movies seem to have weak scripts deliberately, as if they are saying it's okay to have a holed story with weak characters cause we are horror. I just cannot stand that deliberate lack of effort. But that's just me. However some horrors I really like, like The Silence of the Lambs, Alien (the original), The Excorcist, Carrie, The Fly, and the original The Texas Chainsaw Massacre was pretty creepy.
However, I find these horrors to be much better written than the ones at these festivals. They are just more ambitious and a lot of horrors lack ambition.
Now you ask for a new filmmaker which genre is better. I guess the people have spoken and that it's still horror perhaps.
