Though I understand wanting to know if there are differences, considering how your cables are not run through, I , personally, would not consider thinking of the other choices until everything settles in.
I do understand that you want to have the best, but there comes a point when it can become a bit obsessive.
(FWIW, every step up with AQ delivers a noticeable, and usually positive, change).
My 2-3 cents...
