The Mamiyas incl. the expensive adapter seem to be still cheaper than the Canons.
I don't know how cheaply you can get the Mamiya's, but I got the 200 APO for 400 euros and I've seen a Canon 200/2.8L for 390 (but maybe that's an exception).
Differences in size and weight of the 200 Mamiya vs Canon:
1100g vs 765g
91x144mm vs 83x136mm
77 vs 72mm filter thread
no tripod mount possible vs tripod mount option
I don't know how flare-resistant the Canon is, but the Mamiya suffers from veiling flare in backlight situations. I only have the built-in hood atm and I don't know how much a longer hood will help.
I'm certainly impressed by the uniform sharpness of my Mamiya, it really renders a lot of detail, from f/2.8. Bokeh is really excellent.
