Dominator is cooler in design, lawgiver is cooler in capability.
That makes the lawgiver more appealing in functionality, with the voice command changing ammo. But the dominator doesn't blow up and take your hand(s) off with it if you are not licensed to hold it, it just doesn't work.
Both guns are equally interesting to me.
Changing ammo I'm allowed to use is changed by voice in lawgiver, not by sybil system reading, THIS is where the lawgiver really outshines the dominator, in an otherwise nearly evened match.
I'd give it to the LAWGIVER after this comparison, by a small margin.
