Makes me laugh when people try and tell you that do be a real photographer or to be seen to be a real photographer that you need to shoot manual. Its rubbish. You need to do what gives you the results you want. Any time I take a photo I always watch my shutter speed, iso and aperture anyway, I could just about guess what the camera meters before I take the photo.
There is benefit when starting out to shoot manual and av and tv to understand the relationship between aperture, iso and shutter speed.
The main thing is, that you need to be ready, or you can miss the moment. Shooting in P or full auto is better than shooting in manual and under or over exposing the shot.
When I am trying to capture a fast moving bird in the last thing I want to do is fiddle around because the bird has suddenly moved into shadows from a highly lit area, so it satys in av mode mostly.
When I do use manual which is mainly indoors to keep shutter speed up whilst trying to get as big a dof as possible, but still trying and prevent motion blur, I generally put the camera to auto iso.
Funnily enough the 7D usually has the 70-300 on it ( use it outdoor for wildlife ) is mostly in AV, f 7.1 with iso at 800 and the 6D with the 24-70 ( indoor or portrait ) mostly in manual with aperture at f4 and shutter speed at 300 and auto iso. I can then easily adjust shutter speed or aperture as required, by just moving one dial.
