Purchase: 60D or 7D + Lenses?

I use a 60D with a canon 15-85 and a canon 70-200 f/4 L.  Both lenses perform very well on this camera.  Used to have a 24-70 f/2.8 version I which produced jaw dropping images but it was very heavy.  Colors were better than the 15-85, but not much.  I don't care for primes personally, but that's ok because the 60D has lots of noise over 400 ISO anyway.  Tried a 7D about a year ago with these same lenses and I thought the lenses were messed up.  Very soft images.  Exchanged for another 7D and had the same results.  Went back to the 60D a few of times after trying out different cameras.  The images were instantly sharper without having to adjust or mess with anything else, right out of the box, every time.  I also just tried out a new 6D with the 24-105.  Uh, no thanks.  LOL  I was looking at the images on my screen just shaking my head.  For that kind of money, they should be much sharper.  Is it just me?  I don't know.    Anyone else have these experiences?  All I know is when I go back to my 60D and these lenses, all these problems go away.  I guess I just like cameras that I can take out of the box and get sharp images without having to micro adjust, or send back to the factory to have it calibrated.
