Skip the 7d (maybe)
I had both cameras, and just sold my 7d - so my t2i (get a grip!) is my workhorse at the moment until i replace the 7d. Everyone says that both cameras uses the same sensors, but there is a DRAMATIC iso noise difference if you are a pixel peeper. The 7d's images are a mush fest compared to the 550. The iq differences relate to how the 7d sensor pushes the highs, leading to wonderfully contrasted images. But look into those shadows...uh oh...the noise is ugly. 7d iso 100 noise alone should keep you away from it....its really really bad. So bad I sold my dearest.
IF you are a pixel peeper, stay away from 7d. If you are not, then go all in. Its a fabulous body. The handling, is just awesome..its an absolute pleasure to handle.
So I think your 550d focus issues possibly come from your lens (sigma? not surprising) and possibly technique. With both of my rebels my hit rates are north of 80 percent, and thats for fast moving people in the street with endless variety of lighting conditions.
I LOVE my t2i.
At the last fashion week, photogs kept asking me what body i was using, as it has the 70-200 2.8 mk ii attached to it...and i kept saying, dude, its a rebel....yup!
Last year i took the 7d to Singapore. This year, t2i all the way.
