I actually own all 3 of those knives (even the blue Delica) and I really am using the Delica more than the PM2 and the Sage1. The Delica is one I always seem to grab when I head out. It's a tough knife that will stand up to most if not all of what I put it through. I prefer it because it's light, slim, and not too costly (ie. if were to get lost). If you prefer a g10 or CF handle then go for the PM2 or the Sage1 of course at higher cost, but honestly Delica is a great choice of EDC, I'm sure you will enjoy it.
