seriously now... any TATL aircraft that does not offer powerport in Y is inferior, irrespective of the size of overhead bins.
I personally find the A330 much better than the 764. DL gave priority to the 764s in the refurbishing; why some of these still don't have nose-to-tail power is beyond me. Moreover, the interior of the 764 is not standardized and I find this irritating: powerports or no powerport? The exit row seats are much more interesting on the A333, and there is even two seats (11C/G) on the A332 that have essentially infinite legroom. I also much prefer the 2-4-2 configuration.
