Yeah the Gladius is the one that I only use for fun, as it isn't as useful as I might like.
It's combo of energy and kinetic damage are really nice, and at least having the one flare is better then having none at all.
But other then that it doesn't have much going for it. Only two craft per wing, not very tanky, low flux cap that gets filled quickly by the laser, no shield generator, not massively fast and so on.
I WANT to like it however, I just kinda find it not being all that great over the alternatives for any reason or another. One flare use isn't bad if paired with bombers anyway, but it's not like it's better as an escort. And as a gunship I can't say it's sustained fire-power is that impressive even against pirate clunkers.
