The blizzard board is primarily for gel work (though works perfectly fine for L&P) and is white so you dont get any black bits getting stuck in unwanted places.
The Boomerang buffer is a thick and padded 180/180 designed for surface refinement and the Boomerang Board is a thin, larger version of the Koala buffer (240 grit on one side, and a treated 1200 grit oil buffing side on the other).
All the abrasives use a new softer grit. The grit count is the same so the particle size is the same, but the material is actually a little bit softer. This creates less damage to the enhacement during refinement.
Personally, I love the crap out of them
Hope this helps
