I did English Lit to AS level, but I dropped it a couple weeks ago - it's just not my thing. I did enjoy it, though, but I think it was pretty hard. There's a lot of things to include in the exam, but one section of it is formulaic, in a sense.
One reason I'm not so keen on it is because of the marking scheme. It seems to depend more on the examiners opinion of what a good point is rather than the point itself, and it just seems really subjective to him/her. I guess with something like History, there is a definate answer. History seems a little more academic, though.
