To be fair, the Pop card is good for what it is. Which is basically a contactless bank card. You just top it up and pay.
Other than getting a Metro season ticket, there's nowt else it does.

I never understood why GNE didn't just work with NEXUS to allow tickets to be loaded onto a Pop card rather than having to have a separate Key card.

I'm sure Arriva and Stagecoach had their own separate smart card system as well. 

It would have made much more sense to have the one card that can be loaded with different tickets, like you say, you could load Network One tickets if you wanted multi-operator tickets.
