Ordinarily, I would say Camacho, but Pep knows the ins and outs of certain things to get away with in the ring, so I think this would help him win a close SD over Hector.
I wouldn't pick many people to beat Camacho at 130. He was one of the fastest ever. Pep ranks higher historically, but in a h2h fight, I'd go with Hector. He was fast and had more power.
On boxing ability, Pep is on a completely different level... Camacho`s natural size is obviously a big worry though.
