What is the hardest hitting 12 " sub out period that is durable and 1000 + watts RMS?

Only comments from experts or people that know their stuff. Serious comments only! I am looking at the following subs: Critical M UL12, Cerwin Vega Stroker Pro, Digital Design 9512 or Z, Orion HCCA 12.2, American B HD, Mmats Juggernaut, Image Dynamics MAX D2, Memphis MOJO, Kicker Solo X to name some. I WANT TO BE THE BEST ONE SUB AROUND! I currently have 2 Diamond Audio HP12's. They hit good and loud but my installer had a single Stroker 122 or 124 that sounded and felt louder than my 2 DA's. I WANT TO BEAT HIM, NEED HELP?
