Sadapay vs Nayapay

I've been weighing the pros and cons of each but still need some help How much is the tax on each really?

So far pro for Naya is that I get a receipt on my email for every transaction and no limit on receiving amounts amount

Pro for sada is "less taxes"

I paid 1181 on sada for netflix this month. Used naya last month and it deducted 1347

YouTube Premium on Naya cost me 1025 as well

The taxes seem to be applied more extensively on the PKR amounts as opposed to USD

At the end, I'm looking for convenience of use.

Any suggestions?
