Which is harder: LSAT, MCAT, GMAT, GRE, other?

I've taken the MCAT, LSAT, and GRE. I did about the same on each of them. The MCAT required the most studying and would certainly be hardest for someone coming in cold. The science questions aren't hard, but you need a pretty good grasp of the fundamentals in a number of areas (bio, chem, ochem, physics). I think the logic-type problems on the LSAT were a bit harder then those on the GRE. GMAT, meh.
