Apples and oranges honestly....
How did it take so many posts before somebody posted the correct answer?
More specifically, it's like comparing a fat, juicy, over-ripe apple to a rocket-propelled orange made of granite with a titanium skin... and machineguns glued to it.
Speaking as a Corvette fanboy, the Cutter is almost certainly still the most dangerous ship in the game.
Basically, the only way you're going to beat a Cutter in combat is 1) if it's a lousy build, 2) if it's being flown incompetently or 3) if the Cutter jockey dies of old age while you're trying to deplete it's shield.
It's kind of weird to think there might be people who think the Cutter is just a cargo ship.
