NISA in PayPay vs Rakuten

Hii! I’m planning to open a NISA account and need some advice on whether I should go with PayPay or Rakuten. So far, I’ve been using the PayPay ecosystem for most of my payments, including my credit card. I actually tried applying for a Rakuten credit card before, but I got rejected :')

From what I’ve heard, using the Rakuten ecosystem can be quite beneficial because you can convert Rakuten points into NISA investments

For someone like me who’s already deep in the PayPay ecosystem, where would you recommend opening a NISA account?
