One thing I'd say to any prospective buyer is that we probably tend to
overanalyze aspects of
DVC ownership here on the DIS. We criticize DVC guides for overemphasizing features of limited value (like exchanging out via RCI), but we do the same thing sometimes with technical aspects of the program. The only difference is, we're not trying to sell you anything.
Use Year has been under a lot of scruitiny recently because of the recent "streamlining to enhance the ownership experience as a result of member feedback"

by the imposition of the "Rule of 4." Just because one aspect of the program is getting a lot of attention lately doesn't mean it's the most important consideration in a purchase decision.
The fact is every DVC contract has a UY and that is
one of the many things we have to learn about and manage.
If an owner is not knowledgeable (and a LOT aren't) or if we fail to pay attention to little details like banking deadlines and cancellation policies, we're likely to have difficulties no matter what our UY is. Obviously, some UYs provide more flexibility for some months of the year, but all of them limit flexibility the last four months of the UY and all have to be managed.
In a resale decision, unless a UY is just plain horrible for your carved-in-stone vacation pattern, there are probably a lot of other more important considerations to evaluate. That doesn't mean questions shouldn't be asked and answered, but keep things in perspective.
