I personally think that it depends on what genre you play, im guessing more metal so id go look at the Dean as they are more based on the metal sceane, espically with all the dime guitars they are whoreing out nowdays.
Gibson are more suited to rock and hard rock, though some gibbos are good for metal though you will probably have to pay through the arse, depending on what you are looking at spending, maybe Epiphone could be a better option to look at then Gibson.
Anyway, try out a few of each brand and see what you feel best with, its really a matter of personal preference, just go for what feels best for both playabilty and sound.
