Tokina has worse sharpness than Sigma at open apertures and has much higher chromatic aberrations (probably because Tokina uses just 1 ED element while Sigma 4). And Sigma has much faster AF thanks to true IF, is lighter despite having very good build quality (not as tough as Tokina, but much better than any amateur FA zoom, it is more like FA* zooms) and has more usable petal bayonette type hood (Tokina has screw-in type AFAIR).
