I\'ve both and love them for different reasons. If I want to shoot moving persons, I use the Sigma because its AF is fast and precise. If I can take my time to manual focus and need even more shallow DoF, I use the Rokkor.
Sigma:
+ AF
+ smoothest bokeh
- f/1.4 (most of the time it doesn\'t really matter)
Rokkor
+ better colours (less time neede in PP)
+ better aperture and focus control while filming (5D-II)
+ f/1.2
- needs live-view from 5m -> infinity (the mirror is still intact)
- MF only
Another + for the Rokkor (and all MF-lenses in common): I take more time to compose, so more keepers (I could also use MF on my Sigma....).
So for me, they have both their goods and bads, but ymmv.
