DivD is way more specialized than PR.
OG diamond is described as digital Viagra. Make you hard as a Diamond. It’s a sub for more intense sex.
DivD adds a spiritual connection to OG Diamond.
But I don’t see how DivD would shine as much while shopping groceries, changing diapers or enjoying a movie. Of course, it has general scripting, but it’s much more focused on sex then anything else.
Whereas PR is aimed at your relationship in general, while it also contains scripting for better sex.
Also PR is brand new tech, whereas DivD doesn’t have any NSE scripting.
