My come back into knife collecting started with the PM2. I then tried some other popular brands ($30-$290 range). I ended up preferring many of the BM offerings under $250. I keep trying to increase my Spyderco collection though.
IMO, the BM 908 is a better competitor to the PM2 than the Grip or 940. However, the blade steel is 154CM (unless you get the much more expensive M4 version from KSF). I have both (and plan on picking up a 3rd), but they are discontinued, although you can still find a few left online.
I also have the M4 Manix 2. It's handle slopes down more than the PM2. I just prefer the rounded handle feel, blade to handle ratio, no choil, and Axis lock combination of the Benchmades... although many people are the opposite.
I can't find fault in the PM2, and it is available in many great options with terrific fit and finish. I just rarely use it. Of my 4 Spyderco knives, if I could only have 1, I would choose the Military... but that is a fairly large folding knife, and I would probably grab the HAP 40 Stretch for most work duties not related to cutting wood... also if I could only use my Spyderco knives.
Right now my general use folder is a Boost which I don't mind getting knocked around.
