You can make the answer say about anything you want with different assumptions and factors. That said, often these type of calculations assume options that may not be true in 10-20 years and that's part of the risk. They also tend to ignore the time value of money which will favor the cheaper options going in. Then there are the options that would allow one to own less points to accomplish the same stays and options that one could use that are cheaper and accessible no matter where you own, like OKW usage.
Personally I would include the TVM/Opportunity costs and a 3.5-4% increase in dues. I'm not sure I'm OK with assuming any real value in 10 yrs, esp for HHI or VB. I'm certainly not OK assuming an increase in value the next 10 yrs like we've seen the last 10 years. Historically I've done calculations on various resorts. With those thoughts, SSR will be the cheapest long term, BLT second and OKW 2057 will be fairly close. At 10 years it's dependent on resale price and options, risky for HHI & VB. Actually HI & VB subsidized are likely to be the cheapest. Assuming WDW is the goal, SSR will be the best value. Considering usage, SSR used for standard, AKV for value and BWV for standard will likely come out ahead if you buy the lower points.
Ultimately it's still an expense with significant cost and long term risk and one needs to be able to afford both to participate.
