Seems you're leaning more towards primes and/or fast/high quality glass. Under these assumptions, a FF body is a more solid proposal.
In the case you prefer to pay less money for the body though, the option I would recommend above all would be the 70D. It is a very nice camera, well-thought out, and the few minor weak points the 60D had, have now been addressed in 70D.
Having said that, a x1.6 crop sensor camera was, is and will always be a compromise. Nothing beats full frame, this is the truth.
From full frame, the 5D Mk III is undoubtedly a well tested and proven tool - recently the price had another drop, so now it is even more competitive. One can of course go the 1D way, but that's a move to a completely different level of approach, and not many are into this.
From APS-C, my take is that the 70D is a very capable and quite new/fresh camera. The 7D is perhaps faster but it may well be replaced sometime this year.
Above all, go out and try, feel the cameras in mind. Nothing beats your own solid opinion on how the ergonomics and overall touch of each body feel in your hand.
