What is the advantage of the 284 vs. the 7mm-08?

Around 200 fps in velocity?

If so, what value does 200 fps of additional velocity add?

Since I hardly ever shoot anything over 300 yards, except for pdogs and the occassional coyote, 200 fps would be meaningless to me, from a practical POV. For guys who, on a regular basis, shoot things at greater distances, every fps of additional velocity may be very meaningful. But not for shooting game within 300 yards.
