From a layman's point of view, I'm more interested in antimatter's potential as a weapon.
Not necessarily because I want to use it, but because I have a vague idea of what it's capable of, and what that would mean in the hands of certain groups capable of producing it.
Not that great. Chances are you will destroy your country before you destroy some other.
The big advantage of nuclear weapons is they are very cheap per unit of energy yield. Bang for the buck, if you will.
Antimatter production is so inefficient that they will be much more expensive per unit energy yield.
