I shoot professionally with at 7D almost daily, and the reason I chose the 7D at the time were its ability to use multiple different frame rates. This was before the firmware update for the 5D and no one really thought it was going to get one. If I had to do it all over again I would go with the 5D simply for the lens choices and the fact that it is better in low light than the 7D. If I was going to pick one to dive with???? It would be the T2i for the reasons mentioned above. And as far as a production house being able to tell what it was shot with without peaking at the meta data.... Not a chance if it was lit and framed properly. The Data rate for the 7D is actually higher than the 5D due to its dual processors. The 5D has a larger chip with less mega pixles which makes it more sensitive to light and has a better lens selection on the wide end of the spectrum those are it's only real advantages.
