The question is, 1. who wins in a head to head matchup? It seems to me that Hermit/MS would win. Maybe (probably) a mix is better than both. 2. who wins more often against other strong strategies?
It seems to me that Hermit/MS is more resilient to junking, but less resilient to discard attacks. Apprentice/MS, OTOH, is more able to incorporate other powerful stuff (like Goons, Bridge, KC, Possession), so its not a strategy but a combo that can run different strategies. Also, App/MS can use support a lot, while most cards do not help Hermit/MS too much.
