In checking the date my family will be arriving at WDW in 2020 (late August), these are some rates:
All Star Movies: standard room: $125.00
POP Century: standard room: $163.00
Port Orleans Riverside: standard room: $249.00
If I'm planning a family trip on a budget and I'm staying a week, I think the $86 daily difference between POR and POP could still add up to something worth considering. A 7 night stay would mean a $600 difference. I see that as enough to differentiate between POP & POR, personally.
And if you need a better value than that, then the All-Stars are another $38 a night cheaper for this particular week, which shows that the pricing for POP & All-Stars are closer than the pricing for POP & POR.
So I still see POP as a value, just that they allow us to have choices within the "value" category...just as we have since POP & AoA were first built, since they have always cost more than the All-Stars. There are different price choices offered within the other categories, too. Not all deluxe resorts cost the same amount, for instance. I think it's nice that WDW gives people looking for a lower priced resort that kind of choice, too.
I disliked it when the values were only the All-Stars, because theming aside, they were all the same exact resort. I felt like if you wanted a value resort, back then you basically had just one choice with different decor, so to speak.
