alpine type x 12s vs w7s vs 9500s

Wow! the has been an interesting topic.  I have another question to introduce.  I currently have a Premier TS-W5000SPL.  The big daddy.  This sub has done what I've asked of it and more. (shredding records and taking beatings while maintaining very admirable composure)  Though I think I am ready to sell and look for an even more SQL friendly sub.  I want to stay with  a single 12.  My research thus far has led me to the following conclusions. 

-JL 13W7 = The BMW of subs, expensive, but you get top of the line luxury and performance.

-MTX 9500 = Made for SPL, advertise SQ, but I highly disbelieve the SQ claims.

-Eclipse = Evidently well rounded, but I'm not sure I've had enought experience with them to gain my trust.

     and last but not least...

-Adire Audio Brahma = Many records I've set with Adire (before they became known with car audio)  I put them right   up beside JL, but I want reassurance that their Brahma's SQ equals or surpasses JL's W7. 

For the time being, I am looking to size up the 13W7 vs Brahma 12.  I do belive the brahma will post higher numbers, but that means nothing if it doesn't sound good doing it.  Any advice that might sway my favor to one or the other?  Thanks in Advance.

Lets not forget about RE XXX and IDMAX.

On the topic JL=money, When compared to RE XXX, Adires brahma, and image dynamics IDMAX; The sound you get from the other three is better if anything equal that the w7, for the money.

Dont get me wrong, JL makes some fine quality products.  And so does RE, Image Dynamics, Adire Audio, TRU technologys...etc.  It all depends on the listeners ear. 

Is it the general concensus that one 12" Brahma would have higher output than one 13W7?  I realize that the SQ comparison is a toss-up for listener's preference, but wasn't the Brahma designed with more output in mind?  Thanks for all the info.
