I own both. They're so close in price it's gonna come down to preference. I don't find the PM2 entirely comfortable in the pocket because of its size...it is very tall. That said, it's a more comfortable knife to hold than the sage 1 IMO. As for quality control, they're of equal build quality. I like the grind on the PM2 better than the Sage. I carry my Sage only on weekends when I go out because it's classy looking and unobtrusive even in suit pants. The PM2 is a tactical/working knife that some people may look at funny.
There's one knife I carry far more than either of them which I bought after both of them, and that's the Doug Ritter Mini Griptilian. It's just an easier knife for me to live with on a daily basis. YMMV of course.
EDIT just saw you bought the Sage. How do you like it?
