Not sure how to phrase this in terms of the OP but one of the most important things about the Krait is how sensitive it is to heat management.
Build one right and you won't even know what people are complaining about.
Over-do the PP overcharging or the high-energy weapons, however, and heat will become the bane of your existence.
What else?
Well, the ship's design means it's super-easy to scoop cargo, including from planet surfaces.
On a (vaguely) related note, the combination of hardpoints, armour/shields, agility, jump-range and slots means it's pretty-much the ultimate scavenger ship IMO.
You can build one with decent weapons, stick a collector controller, an SRV and a 0A wake-scanner on it and you've got one ship that can jump all over the galaxy, farm USSs, Famine dist' sites, crash sites and CNB's for mat's.
More mundanely, I believe the dev's have officially stated that it's a ship which the authorities will pay little attention to at stations/outposts so it's probably a good choice for smuggling.
