Is there an actual advantage to BBP vs SBP?

I bought a spare rim with the dual bolt pattern to solve my problem. I have the large bolt pattern on the front of my Cuda (4 1/2") and a Chevy 10 bolt rear end (4 3/4"). The spare rim has both bolt patterns and I'm happy!!

But now try to find a wheel with 5x4" and 5x4.5" on it.
