Try try em both and look on vimeo for samples of different cameras work. What I would say though is if you are on a budget then get a 60D (or even 550D) which is cheaper but spend money on a decent zoom and a fast prime or 2 then when/if you start to get work then you can upgrade the body to a Mk2 but the main thing is to have nice lenses. No use crippling yourself financially on something which you may not require.
