The problem with having a B-wing that can one shot a large imperial ship, is that it kind of obsoletes said imperial ships; yet, we see the Empire continue to field these large ships throughout the original trilogy. This opens up another can of worms which some thoughtful planing on the part of the writers could have avoided. In the meantime we're left with fansplaining to make sense of all this.
Star Wars always required copious amounts of fansplaining to make any kind of sense. This is why you get explanations of the Kessel run involving a cluster of black holes because lol. Or private fab shops producing the equivalent of the F-22 because lol. Or etc.
Han's statement makes more sense if you know it's BS trying to impress Obi Wan. Both Obi Wan's reaction and the script spell it out. Leave it to dumb SW nerds to take everything at face value.
