If I have a credit card, as a consumer Stripe and PayPal are about equal. Both let me pay with my card without making an account. Both will lightly nag me to make one, with the difference that Stripe Link is very light-weight and Paypal is a lot more heavy-weight. But in return Paypal allows more payment methods (direct debit from your bank account being a big pull here in Germany) and makes it possible to send money between friends. Also lots of people 30+ (which is the vast majority of the population) have paypal accounts from the "don't give random websites your credit card, give it to this one trustworthy website instead"-era.
If there weren't so many people hating PayPal, I'd expect a straight Stripe/Paypal choice to lean much more towards paypal, not a 50-50 split
