You'll hear about a 50/50 split on this one.
I've only visited AKL, and while it looks nice, I don't like being that far away from the other parks. Odd thing is, I've stayed at All Stars which are just as far away many times, but it still feels like Disney to me.
AKL I would guess has better bus options, as they don't share with other resorts. WL shares with GF. However, WL has a boat to the Magic Kingdom, so that's a huge plus.
From what I understand, AKL has the better quick service option, though WL is just fine.
Location, WL wins hands down.
