IQ of the 80-200 2.8 L vs the 135 L

Anybody compare the two? I was going to pick up a 70-200 at some point, but found an 80-200 for a good deal. I may have to let my 135 go for now to get it though. Any help is appreciated.

Never owned the 80-200 but did have the 135 a bit. I think most people would regard the 135L a step or two above the 80-200. The 80-200 is a well-regarded lens in general, I believe, but the 135 seems to be becoming a progressively less popular lens as the xx-200 line evolves. Meaning it was most popular at the time of the 80-200.

As an amateur, having used the 135L and 70-200L, if I could keep only one lens, I'd definitely choose 70-200L. To me the flexibility of the zoom is much more important than the incremental PQ improvment of 135L.

It sounds like I need to hang on to my 135L for the time being, and then get the 70-200 IS II when I can.
