Rib Types

I’ve seen two patterns for a basic rib scarf. Both cast on 36. One pattern is k2p1. The other pattern is p2k1. Is one better than the other?? Sorry to ask a question I should be able to figure out on my own, but I have an early flight tomorrow and want to take a project with me.

In ribbing, one side of the scarf would be k2p1 and the reverse side would be k1p2 so the two rib types sound like they might be opposite sides of the same scarf.

Have a good flight!
