More cone area always makes a differance. Then your electrical,amps,box design the music you listen to also make it a factor. It don't matter how loud on the outside. It matters how it sounds on the inside. I can take two cheap Sony explodes and in the right box make them just as loud as kicker. So what are you really asking? No one can tell you what you will like better it's your ears. Too many factors need to be addressed like car,placement of subs,how you want them to preform,type of music,box etc. If you like more air movement with your system then more cone area with subs of your choice etc. That's my input on it but I'm still a noob.
