1 comp set vs 2 comp sets

i have a delimmia.

i am wondering what would be better for my front stage.

i have a orion 300.2 (75x2@4ohm) (150x2@2ohm).

i have a choice of gettin a set of image dynamics chameleons 6/12 @ 2 ohms (150w)

or

2 sets of 6 1/2 comps (kicker or alpine) that share 75w. One set in the door and one in a qlogic kick panel)

they will have to keep up with a Re Mt 12 @ 2500+ watts....

vote and tell why- thanks
