tricker-dag is a merkle-dag in the definition sense but when we think about merkle-dag we default to thinking about balanced tree DAG. This isn’t the case in with trickle-dag that has other structure (list-of-lists).

I guess I mean, what is the effective difference for the user: when should trickle-dag be used?

Trickle-dag is optimized for reading data in sequence, while the merkle-dag improves random access time. It might make sense to use trickle-dag for long videos, but in my experience it’s not a massive difference.
