One thing to consider is that the Sigma is sharp at f1.8, whereas tha Canon is not sharp until about f3.5. I have the Canon 17-55 and while a good alrounder, I find the wide open performance the main drawback.

I am considering moving to the Sigma, as I'm shooting photos of kids and they move, so IS is of less value, but the ability to shoot 2 stops faster shutter speed is of more benefit. Just wish that the Sigma had a longer focal length .... but we all need to make compromises

This is a hard decision for me as I don't have either and I have to choose one!  I'm actually leaning towards the 17-55 right now due to having IS.
