Really nice article, thank you! We are researching which of the 3 mentioned platforms to use as well and I think the most important aspect is figuring out all possible use cases before deciding. In our case we already have Firebase products so it seems simple to go with Firebase Dynamic Links, but the fear is we may need a more robust solution in the future, like Branch. Otherwise, your URL structure and Deep Link handler are smartly thought out, and a nice example to follow. Good work!
