Assume that you would like to use journey data once again in AEP. I see that there are two ways to update AEP: 

  1. Sent data from journey: Custom Action → AEP Streaming API
  2. Update Node 

What are the differences in you use-cases? What you prefer?

This comes up a lot when people want journey execution to feed back into the Profile/Data Lake in AEP. 

Update Profile is native and writes only to the Profile Store (own dataset, slight delay, no branching).

Custom Action > Streaming API is a per-profile REST call that can also hit the Data Lake and lets you branch on the response, but doesn't scale well.

Update Profile is better unless you need Data Lake writes or response-based branching.
