We have stayed at both and honestly...it's toss-up (DD leans toward WL, I lean toward AKL, with DH and DS undecided). There were things that we liked better about each.
The distance between AKL and the parks is not enough of a reason to choose WL. We found the bus transportation equal to all parks except MK and AK (with WL having far superior transportation to MK and AKL having far superior transportation to MK). It was the same to the other parks. We thought the boat to MK from WL was way overrated and after the first day, we used the bus. Restaurants are always a matter of taste, and no matter where you stay, you can always dine at the other, but I would give the edge to the food at AKL (we actively disliked WCC, loved Roaring Fork and Artist Point; we love Boma and Mara, and are divided about Jiko).
I agree with the previous poster who suggested you go with the theme that appeals to you most. You really can't go wrong with either!
