My choice was the 100-400 avoiding the use of converter and having a wider range in one lens. The had IS while 70-200 had not. The quality of the lens is really very good - better at 400 than the 200 plus converter- and the only issue is the zoom system that allow dust easily coming inside the lens. Only if you need the 2.8...
