But ... but ... I like both.

There is good and bad in both genres.

I would say that writing good SF is harder, because you must first know some good science, know where the cutting edge of science is up to, then stretch your imagination beyond that, being creative yet keeping it at least "possible" given what we know about science so far. And then be able to construct an interesting plot and believable characters, and then be able to write well.

And I know that if you want to look like a real geek you should call it SF not SciFi. Dunno why though. Geeks can be pretty snobby sometimes.
