In the days before the 70-200/II, the 200L got definitely a lot more action than since the mk2 zoom moved in, that's for sure. I'd say that the zoom will get you 90% there at a fraction of the cost and weight. However, for the special occasions I still bust out the prime.
I never shot the 200/2 at anything other than f2, so I can't speak to its sharpness stopped down.
I agree with this one too. Since getting the 70-200 II, I use the 2.0 a lot less. However, there are certain circumstances where the f2.0 allows me to document certain low light events without having to push the ISO too far. Love having the 280 2.8 when needed also. Would be hard to give up either of these lenses now that I have them.
When I got the 70-200 II, I did sell my 135 2.0 which I loved and sometimes miss. But you can only carry so many lenses!
