Coming from someone who has stayed at the All-Stars 5 times & the Moderates twice (PO-R and CBR). I find that I enjoy the Moderates better (as long as I am not paying 50% more). Both times we stayed at the Moderates, we paid under $100 per night.
I enjoyed the All-Stars and will probably be staying there again in the future. However, our favorite resort is the CBR.
In my opinion, the Moderates have a better layout and landscaping. I also didn't feel as crowded. I am sure that CS is the same. (We are actually planning on staying there next year). Plus, the rooms are bigger the All-Stars.
The number of days may be a limiting factor on how you much you enjoyr your resort. We typically stay 7 to 10 nights each time we go so we have at least one day just to enjoy the resort.
Don't forget that switching in the middle of the stay will mean the refillable mugs won't make economic sense.
That said, we switched resorts one time in the past and had Disney handle our luggage switch. It was a piece of cake and I would let them do it for you. We even had misc. Disney World souvenier bags and a cooler. They moved each item for us, not just our luggage.
