Which Payment Service Do You Use Most?

Payment system, payment service, whatever you call it, these things are super handy to have on your phone. I personally have CashApp and PayPal and like them both, more so CashApp because there is no charge to send money but if you are sending to someone who does not have the same as you, what do you do?

I have an Android phone by the way, I don't know if that makes a difference but these 2 particular apps are the ones I use the most. Is there another I don't yet know about that is better? Which do you use more?
