There is no way to compare an All Stars or POP stay to a DVC stay, even in a studio. My two experiences at All Stars were awful. I stay off site if POP isn't available with an AP discount on the nights we arrive early for our DVC stays. I like POP Century OK, it is what it is, small value rooms, double beds, no TS restaurant (though they do have a very good food court). That said, I wouldn't mind POP for a night or two to bookend a DVC stay, we often do that as we tend to drive and arrive a day early. For a week or longer, I like the full kitchen and in room laundry, though we do sometimes settle for a studio to save points for extended family trips.
Since the
DDP limits what I can choose to eat, the paid version is never of any use to us, it does not fit our dining style, even though we usually have a TS meal daily, sometimes more. For instance, we usually have a nice TS lunch at Brown Derby including 2 appetizers, entrees, 2 beverages, 2 adult beverages, and split a dessert. This generally runs about $100
including tip. Now, BD is a 2 credit DDP meal, so it would cost $100 (if you figure the TS meal credits at $25 per) PLUS appetizers, adult beverage, and tip. Not a good deal on the DDP.
If you're perfectly happy in the smaller accommodations and only food court food at the resort for an extended stay, perhaps DVC isn't the best option for you. If you stay mostly at deluxe class Disney resorts, like having a TS restaurant at your resort, prefer larger beds, then DVC makes sense.
