Optically, they're nearly identical and it would be hard to pick one over the other in that regard. However, the SWD version has curved aperture blades and is considered to offer better (smoother) bokeh than the earlier edition, which can give "gritty" bokeh in certain settings.

Hmmm. I suspect the people who do this particular considering are ones who WANT the SWD one to have less nasty bokeh, rather than ones who honestly look at the pictures!!

Surely the bad bokeh with the 50-200 is a function of the glass/optic formula (which seems to be pretty much the same on both) . The aperture blades merely changing the shape of the OOF highlights

As I mentioned previously, I've yet to see any side by side comparison where the nastiness of the gritty/double stroke bokeh is lessened on the SWD design. I'd be delighted to be proved wrong though as I'd snap up a new 50-200 tomorrow if this was the case. The bokeh is the main failing of what is otherwise an incredible lens.
