Best chance at getting an iPhone 8 on launch day?

Bottom line is, should I order through Verizon or Apple? Which do I have a better chance of getting it next Friday, launch day? First world problem, I know I know…

IPhone has already Launched September 12. So, no chance to get.

No one will be getting it until November. Better hurry, last I heard is that pre-orders are almost sold out.
