Welcome to OSO
First of all, where in the world are you? Whatever you do, you need to take a ride in both boats. They are quite different in size. The Lightning is more like a 32 true footer, when you remove the beak and integrated swimplatform. What is your budget? When you say rough seas, how rough? Abillity to bring x number of passengers? If you don't have one in your area, my guess is you will import one. You will then need to take a vacation to the states and find your boat. If you have the cash for these toys, you have the cash for looking at them. Buying something like this without riding it and looking at it, especially considering you never been on either, would be down right stupid. Not trying to be a stick in the mud, but be sensible about it. You are the one that'll pay and live with it, so you must be the one who likes it.
