Alexandre, Tough call. My wisdom and experience puts the Tokina as the best choice. There are many aspects to a lens. Sigma generally seems to get sharpness pretty good, but has problems in other areas (build quality, compatibility). I have the ATX Tokina Pro II that you mentioned and have found it to be quite good for a zoom. It is very solidly built and fairly heavy. It also has quite good manual focus feel. I don't know how well the Sigma's are in that area.
