The f/2.8 is not sharper. If anything, it seems that the f/4 IS is the sharpest 70-200 variant. I consider all those 70-200 equal, and the question is simply the choice of having IS, f/4 vs f/2.8 and the weigth & price.

IS delivers 3 stops advantage, vs. the aperture 1 stop advantage. Therefor, for general purpose , I think IS will be more valuable than the aperture. Especially on 200mm, there's enough non-static shots that will benefit mightily from IS.

Something not to forget is the weight... 700 grams for the f/4 versions is easily handling, even for long time. But the 1.5 kg for the f/2.8 is really heavy. Maybe if you use it a lot, you'll grow some muscle, but for more occasional use, I prefer the lower weight.
