I am trying to understand why you would say archetypes are better than persona for discovery phase?
Maybe because you understand that personas are fictional and archetype are more based on actual behavior as these are modeled from typical users. In this case, answer is no. Personas are just as much based on actual behavior as archetypes (or they should be at least).
I think of archetypes as an average behavior, where as persona as a set of distinct diverse behaviors. Henceforth, for divergent brainstorming, personas are obviously better.
