50 1.8 vs. Tamron 28-75 Di??

Has anyone performed any kind of IQ test comparing the Tamron 28-75 2.8 Di lens against the Canon 50 1.8 II lens? The Fred/miranda site has the Tamron up by a very small margin. Photodo has the 50mm rating as high, but only has users reviews for the Tam.

Should I expect to get the same quality image form a Canon 50mm at f2.8 (one stop down from wide open)as I would get from the Tamron 28-75 at it's 2.8(it's wide open setting)?

I've been thinking of getting the Tamron and ditching the 50mm (and a second lens) in order to travel with just the one 28-75 zoom. But if the 50mm can deliver better IQ at, what is the widest setting on the Tamron(2.8), I may not do this.

Any advice? If they are equal at 2.8, the 50 goes. I don't need the extra stop that the 50mm has, and the zoom doesn't.
Thank you
