I have had the 80-200 f/2.8L /70-200 f/2.8L and now the 70-200 f/2.8L IS II. I have also had or currently own the 100 f/2.8L, 135 f/2L and 200 f/2.8L.
I would boil your question down to what is more important to your shooting, flexibility, or the specialized qualities of the 100 and 135. The 200L is a wash with the new zoom.
There are times in professional shooting and/or high action situations where I need the flexibility of the zoom to adjust framing on the fly, especially when my mobility is limited by the event or circumstances. This week's paddlesports shoot with kayaks and paddleboards on the Charleston harbor is just such a situation. With choppy water and multiple boats, I needed the zoom capability to maintain a good composition. shooting with the 135 or the 200 would have made a much longer day out of it.
On the other hand, there are situations where I absolutely need the macro of the 100L or the f/2 of the 135L. For their given focal lengths, there is nothing really to choose between the three primes and the zoom. It really is the close focusing ability of the 100L that sets that lens apart. You can really move in on a tight headshot and drop backgrounds out in a way that the zoom can't in close quarters. And, of course, you can get tight on small items like rings, flowers, hands, insects, etc. With the 135, unless you've seen your image at f/2 vs the f/2.8 you can't know how special that is. I love to shoot athletes in forested trails with that lens. Even when the trees are close in, that lens lets me separate the runners at much closer range than the zoom. Same thing in crowded wedding scenarios. I can separate the couple on the dance floor from the sidelines even when they are surrounded by other guests.
Are those two qualities more important to you than the flexibility of the zoom? I think for personal shooting, unless those two things are extremely important to what you want to shoot, the zoom is going to be a better choice for the long run.
With that said, if someone said I had to choose one way or anther on my lenses, I'd drop every zoom I have and go with the 35/85/135 trinity and throw in the 100 for macro. I like the discipline of single focal length shooting.
