Your installation is going to make a bigger difference than the speakers. If I couldn't hear each set, I'd narrow it down to hard/soft tweeter and take your preference first, and then as a tie breaker the set with better midbass extension via the rolloff on the frequency response. Again, installation I'd think about first. Are you installing these IB in the doors or kicks, in a sealed/ported enclosure, what are the mounting locations, and is your deadening budget as large as the budget for the drivers?
