There are situational uses when I might favor one over the other but I think they average out.

Is there a better argument for why one would cost more than the other?

Yes. What you really need to do is "what is the fair cost of a +2 bonus" and "what is the fair cost of a +4 bonus". The cost of the second stackable bonus is equal to the difference between those two values, and the cost of a +4 may not be twice the cost of a +2.
