My first question OP is, do you spend all your time in the parks or do you spend a lot of time at your resort? If you are spending your time in the parks, it makes sense to spend less on the room and stay the extra day. If you spend a lot of time at the resort, you may enjoy the larger room size and pool amenities of a moderate over a value. POFQ feels more adult than All Star Music, although I enjoy the theming at both. Since you say you have stayed at both values and moderates before, think about the things you liked, and did not like, about those experiences before deciding.
I have stayed at both resorts a lot. I always end up spending more time at the resort when staying at POFQ than I do at All Star Music. I am also more likely to spend time at DS when staying at POFQ, since getting there is so convenient. Bus service at both is fine, so I can’t say that factors into my decision to stay at one over the other. You just need to think about what you want to get out of your resort on this trip. That is something only you know.
