Currently using a 40D. I have always found its autofocus wanting, and I have to be very particular when taking corporate shots or school socials. I really want a 6D - but one criticism in this calibre of camera was the paucity of focus points compared with 7D. I might be patient and wait for the 6D Mark 2, but this might be coming who knows when, and who knows what it will change. In the real world, have 6D users have want to complain about the focusing on this camera?
