The choice really depends on how well you shoot with open sights. I have a 2x scope on my primary hunting revolver, but also like to go open sighted every now and then. Scope gives you one visual plane to sight on rather than worrying about iron sight alignment. But, scopes are not as fast as iron sights, so if you hunt thick areas, you might consider iron sights. My philosophy, have one of each! Consider something a little bigger than the 357 for the next gun.
