#1

Is there really a question? They're nearly identical, save for the slight speed on the first one. And the, imo, wasted tackle in the second.

why don't either of them have a points in shutdown coverage that would be the tie breaker for me.

Neither of them are very good, but if i absolutely had to choose it would be #1.
They both need agility and some SAs.

#2 if I have to pick, the number of points in tackling is not wasted depending on the type of league the CB is in. They could be facing lot of power runing teams.
I had adjust one of my CB's build for the same reason.

Easily #1. Faster, More Agile, Better CTH.
