As others have said, annual dues and where you want to stay play a big factor. I went through a lot of hand wringing and angst facing the same dilemma you are. In the end, I went for a VGF contract which is my favorite resort vs. a cheaper contract with more points at SSR. I felt that if I wanted to reserve in VGF and couldn't, I would probably end up regretting my DVC purchase.
The other factors that played heavily into my decision was annual dues and expiration date of the resort. While the upfront cost is a significant factor, the way I looked at it was the upfront cost was a ONE time deal. In 5, 10, 20 years, would I resent (or have much difficulty) paying $6.30 per point at AKV vs. $5.52 per point at GFV year after year? To me, the lower dues meant more money I had available for each trip. With the expiration dates, SSR expires 10 years earlier (2054) than VGF at 2064. To me, that extra 10 year represents another 10 years of cost savings, thereby adding more value to my contract.
My best advice is to try to look down the road beyond the initial upfront cost. In 5, 10, 25 years when the upfront costs are spent and forgotten about (relatively speaking), what will you be most content living with?
