Joe Gibbs Break In oil?

I pretty much planned on getting the good ol' Comp Break in additive, but when I was looking for Joe Gibbs oil online, I found out they also have break in oil as well. It says, "no other additives needed", and it's $7.99 a quart.

What do you guys think? and/or which would you use?
