Nope. The Cobra is better in many ways: Smaller target, lower running costs, 60m/s is a huge speed advantage and it carries 1/5 the financial risk of the Asp. In a fight with two equally skilled Commanders, I'd favour the Cobra. The Asp is clearly a better choice for exploration, with a jump range almost 30% higher, but only if you can afford the outfitting and running costs.
Cobras shields are trash tier, ends up spending more time running then anything.
Smaller target. Yay. Thats such a huge boon, considering its not much bigger profile wise. Same top down.
Cost is irrelevant.
Against two separate commanders, if the Asp is not an idiot, the cobra is going to run away. 60 m\ps not that huge of a boon. Only affects you when, guess what, you are chasing cobras. The real boon of the Asp is its ability to mass lock the T9, Clipper, T7, T6, ect.
There is a huge reason why its the go to pirate vessel once you stop being poor. Cobra is a trash tier ship once you have the means to pass it. A throwaway on par with the Viper. Only good for taking on anything up to the T6, which isn't much. Anything else is only humoring you with their time, since you can do exactly nothing to stop them from leaving.
Asp is a straight up upgrade from the Cobra.
