I will say alpine because I am programmed to, and because I want them. I have a T757 V12 and have nothing but good things to say about them. I also know these new models are much improved internally over the already great previous gen V12s. I will say that the RFs look goofy (think cheap) and if you are concerned at all with the install looking nice, the V12 is the way to go.
But I am an Alpine fan (HUs, amps, not speakers or subwoofer, you can do much better in those two departments) so my opinion is just a little biased
