In my opinion, neither will ever be a collector vehicle. The 09 is going to obviously much faster, but the 14 is a much nicer looking car, with a killer color. Both will be a blast to drive, but you have to decide if the extra horsepower and performance is what you want over the V6. If your age and insurance premiums play into it, the V6 would be the wiser choice.
Just saying again, this is my opinion.
