You give the answers already:
You like the extra distance the 150mm Sigma gives.
Both have IS, so both will help a little bit at close up distances with handshake-"ignoring".Is there a store nearby that allows you to handle both lenses on your camera?
If somehow the Canon IS is better in countering the handshake at close up distances, there is a 3rd option: Canon 100mm f2.8 IS + Kenko 1.4x tele converter.
