Discovery weapons are cool, I got a set on my Klingon cruiser and the burst fire makes it feel more true to Klingon style with the cannon burst of things but with it being a beam. I'd like them for Fed side if the color was different.
It ain't on the list, but Pulse Phasers are really awesome Fed side. Very nice visuals and one of the best weapons with it's stats.
I would youtube them and pick what visual you like the best if you are not concerned with min/max.
