So far from what I hear, the Canon seems to be the one with better IQ. When you get a F2.8 70-200 zoom, you really intend to shoot it at F2.8. That is why you pay more, and carry a much heavier lens. Canon 70-200/4 is much smaller and lighter.
Thanks for your input bro, I think a second hand copy of the 70-200 2.8 IS Mk I is what I will get. Since the QC at Sigma is not so fantastic (though I hear it is improving) and the value of third party lenses also depreciate pretty fast.
