which ever one feels comfortable...
people put way too much thought into spikes.
Personally, I like one that's soft, doesn't have a lot of stitching on it, because it's pointless and just adds weight and give you blisters (I'm looking at you Asics), and is flexible (the plate in not 100% plastic).
That said, I think all of the Nikes are a fine choice. So, just go with the one that you like.
The what spike your wearing is far less important than how hard you run while wearing it. You could spend hours agonizing over what spike to wear when that time might be better spent mentally prepairing to go out there in run like hell.
