Hi warwick:
I considered the same choice a few years ago. I really liked the Sigma 150 for its slightly larger aperture and slightly shorter focal length. However, my past experience with Sigma's reliability led me to choose the Tamron, which I've been very happy with (the Canon 180 was just too many $$$$).
My first experience with Sigma was a 400mm f/5.6 Apo in EOS mount; it arrived with a very loose tripod mount and never held up very well - I soon traded it.
My second experience was a Sigma 28-70 lens (a gift), also in EOS mount, worked fine on my Canon Elan, but gave an error code on my EOS 350D. It was late in the lens' life cycle and Sigma wouldn't/couldn't re-chip it. At any rate, the front element fell off in my hands at the dinner table one evening!
I would not consider any Sigma lens in Canon mount as they have a long history of compatibility issues with newer Canon models. I've never heard of any similar complaints on Nikon, Minolta (Sony) or any other mounts.

They do NOT have a "long history" of compatibility issues, that is just not true.
Sigma's lenses worked on all Canon EOS camera until around the advent of the EOS 10D or so Canon made the electrical aperture operation a bit more strict in the signals it would take, and then the SIgma lenses till then started to make the cameras have a problem closing the aperture on the Sigma lenses.
That was a one time deal.
No, Sigma lenses may have a problem on the new Sony A55/A33 cameras.
For the rest, Sigma lenses can be very reliable, of course some lenses more than others. You will for instance never hear about real problems with the Sigma 150mm f2.8 macro, it is a fine lens.
