I love AB, inside and out. The rooms seem to have better theming than mansions IMO (unless you book a royal room). Of course it's a matter of preference, but to me the mansion rooms are a little on the boring side. I know some ppl don't like the rustic look of AB, but I think the extra little details add some Disney magic. (ie: carpet that looks like wooden planks, lantern lights over beds, Murphy bed made to look like crate when folded up with mural of Louis the aligator when open, etc) I do think the grounds of mansions are really pretty, and I saw in pictures that some fountains are lit up with colored lights at night. So like someone else mentioned, check out pictures and see what you prefer.
