Only difference between the two is that the Ghost edition comes with a customized Ghost and the other doesn't. I was the first from my GameStop to purchase the Ghost edition. It's Destiny! Go big or go home. That's how I view it.

That's up to you. The difference between the two editions comes down to physical items. So if you value those physical items, get Ghost. If you don't care about collecting things, then go lower. People have different values on things- no one can tell you what you should value, and there is no wrong answer.
