Approaches to aggression in stocking a 120

[trilinearmipmap]

Planning the stocking of a 120g reef, it will be my first SW tank. I plan to understock because it is my personal philosophy.

I like the look of Maroon Clownfish but they are said to be aggressive, False Percula clowns are tamer but don't appeal to me as much. So which plan makes more sense?

Plan A: put in several different types of scrappy aggressive fish that can take care of themselves, eg pair of Maroon Clowns, Orchid Dottyback, perhaps a Tang.

Plan B: put in more peaceful types of fish that won't bother each other, eg. False Percula Clowns, Royal Gramma, other more peaceful fish.

Plan A appeals to me more if it will work out, please advise me on this.
