I run the transphasics because they still pass as photons with their orange glowing color and thus are acceptable as Federation weaponry for me.
I max my toon within a themed frame, but the theme takes precedence.
Quantums might be interesting, they produce higher damage on blank hull, not sure if they compete against shielded targets, though.
I would enjoy classic reds with some interesting perks.
But in this game it's all about making your toon as unfaction like as possible.
