anything is worth what you are willing to pay. You could go forced induction for the price of a hood like that. What performance are you expecting from a hood? ventilation maybe, but not more than 1000 dollars worth (that includes shipping). That would be how much I would pay if I wanted the carbon fiber look. Fiberglass/urethane hoods do the same thing but for much less money, but are slightly heavier than dry carbon. I don't know, unless you are really into the look, that is really way too much IMO. But do what you want haha it's your car. I'm up in college station, if you get a 6k hood you ought to drive down and let me see it haha
FYI cracking from any manufacturer is doubtful, but fitment issues may occur. However most of the time, particularly hoods from the manufacturers you listed, seem to fit just fine.
