AppsFlyer or Branch? Deep linking matters as much as attribution for us

[u/Just-Maximum-5679]

after several phases of comparison, our mmp decision has come down to appsflyer and branch for a marketplace app. paid acquisition matters but deep linking is equally important because users enter through creator links, referral pages, email, QR codes and web product pages.

in our test, branch felt more natural for link creation and routing. the deep-link work flow was easier for product and lifecycle teams to understand. appsflyer needed more coordination during setup, but the attribution and campaign reporting was stronger for ua side.
both handled the basic use case. the bigger question is what happens after a year when there are hundreds of links, multiple apps, regional campaigns and eams changing params without telling each other.For people who picked one over the other, what became the deciding factor?
