I'm not someone who is interested in VDH or PVB, but if I were, I think this is how I would look at a 150 point direct purchase at either with the primary aim being blue card benefits. I haven't run the numbers to get more precision, but I would think it would look something like this. If I were going to use those points at VDH every 1-3 years, buy VDH. If I were going to use those points at VDH every 5 or 6 years, but for most years, I was going to use it at WDW (PVB or other WDW resorts), I'd buy PVB. To me, that calculus would be based primarily on dues - current dues and the history that we have. And, based on current dues and history of percentage increase, PVB just beats VDH hands down. That's not a guarantee of the future, but that's what we know now.

And, just to put some numbers out there, the trend with newer resorts has been that the dues start out higher, but the growth rate in dues tends to be small - that has not been the case at VDH so far. CCV's CAGR is 2.6%. RIV is 2%. PVB is 3.1%. CFW is 0.4%. VDH is 5.2%. It's an outlier . . . again, based on the data that we have currently. That could change. If you feel comfortably predicting a change one direction or the other, that might influence one to go with one or the other.
The secondary (and far less significant) reason I'd probably go with PVB over VDH (if not using VDH home resort advantage every 1-3 years) is resale value. If I were betting on resale value 20 years from, now, I'd bet on PVB over VDH . . . but, I wouldn't bet much money because that is a long ways away. And, if you're buying direct, I really wouldn't be buying based on projected resale value 20+ years into the future.
So, if you're just talking numbers (and, look, I get the emotional aspect - that's why I won 600 direct RIV points

), the decision between PVB and VDH comes down to where you are going to be primarily using those points. If VDH, buy VDH. If anywhere else, buy PVB.
