Are you planning to go through PayPal directly or Braintree?
One thing I notice is, I get much less fraudulent payments through PayPal, and when I do get them it's handled automatically (and most of the time they end up being not fraud because PayPal investigated it and released the funds). 100% hands free, $0 in fees.
With Stripe, not only do I get more fraudulent payments but you need to pay $15 as a dispute fee through Stripe when you lose the case and pretty much all fraud causes through Stripe will be lost (because it's actual fraud). It also takes like 20 minutes to fill out the forms, create fax-compatible sized screenshots and a lot of other boilerplate information if you plan to contest the dispute.
It's a shame Stripe doesn't offer the Radar service (helps detect and prevent fraud) with custom rules as part of their normal service. You can only get it if you pay insurance fees, which are added fees on top of the normal amount.
Combine that with the new Stripe SCA compatible APIs and sketchy docs and yeah I'm in the same boat as you. Stripe is no longer an immediate "of course I'm going to use Stripe" decision. Braintree is looking pretty good at this point.
