I just wanted to chime in to say that I've stayed at both the value (ASMu) and moderates (POFQ, CBR). This next trip will be the first with my DD2 (less than 3 weeks away - yay!) and we'll be staying at POP.
Honestly, the last trip we treated ourselves to CBR and ended up wishing we would have just saved our money and gone for a value level. Sure, the theming at CBR and POFQ was prettier, but we also liked the larger-than-life, over-the-top hugeness of ASMu. And for the amount of time we spent at the resort, it really didn't matter one way or the other to us. Sure, we got an extra sink at the moderates. But while it's a convenience, we wouldn't really consider that worth the expense. Sure, the moderate rooms were bigger, but I think I would only notice the difference if there were more people in the room, or if some of us were bigger (with just me DH and DD2, I don't think it's an issue). And sure, the moderates each had a sit down restaurant, but if I'm going to do a table service, I want to go spend my money at a restaurant in the parks. So, as you can see, we never really saw the use in spending the extra money for the moderates. With that extra money you can either stay longer, or you can go for better meals, etc. So, during our last trip, we decided that until we can afford to stay at a deluxe (either monorail resort for convenience or AKL), which is something I want to do at least once in my lifetime, we'd just go ahead and do value.
All that said, I also know people who swear by the moderates. I personally just can't justify the expense.
