I tried to give you some useful information. Before I got the 200mm the 85mm 1.4G was my most used lens, and sort of still is as it's a little more versatile in it's length. But if there is room for it, I will withouth a doubt use the 200mm.
The only downsides to the 85mm is it's not the fastes focusing and it suffers, quite badly, from CA when shot wide open. But it's plenty sharp and yields fantastic results when used correctly. I've tried to force some CA from the 200, and I havent been able to, that's pretty amazing in my eyes.
But it's not as versatile as a 70-200, and the 70-200 VR2 is an amazing lens that I have used quite a lot. I recently sold it to fund my second 200mm, so I can't give you some examples. Fortunately for me I usually have time to use primes mostly for my kind of work.
If I were a wedding shooter, I think I would have both in my kit, but a 70-200 would be first priority.
Luckily I don't do weddings!
