Hello @Andrea_Walker ,
There are many variables to consider in properly weighting your options. For example there is a limit of 100 active engagement programs in Marketo.

Does the solution need to be scalable or repeatable for future use? etc.
Why are you leaning to different engagement programs vs streams?
