Now, onto the only merit that really matters between the two. The tac series has a double rail, so if one breaks, it's not a steaming pile. The Shockwave has no such failsafe: One rail, and should it snap you now have a cumbersome version of a tee ball bat.
Just a point of parliamentary procedure, because all I've seen are cut and pastes from websites, but I own three Shockwaves, one in each flavor, and they all have two rails, one on each side of the slide . . .
