I love my P4, and have given away two P4's and two S4's as Christmas gifts.

I chose the P4 because of the pliers, and passed on the S4 for EDC because the scissors was redundant to the knife. Sometimes I regret giving up the scissors because I used to use the Leatherman Micro's scissors to trim my nasal hairs. But in a survival situation, I'd rather have the pliers and let my nasal hairs grow.
