I use sonicfire pro 4 and absolutely love it. Especially the moodmapping capabilities with their new multi-layered tracks. Years ago their music was cheesy, but now it's excellent. Go listen to the Filmcomposer range!
I can't compare or comment on the other tools, but they are really quite different to SonicFire Pro which is a tool to allow you to create perfect length royalty free music, selectable by genre, mood, feel, and tempo.
