If you want a big spyderco folder I would highly recommend the military over the police, I just think it's a better, more ergonomic design (police is a bit too slim for its length) and carries incredibly well for its size. You get arguably better steel with the military as well. The military and paramilitary 2 are made in Golden Colorado if that matters to you where as the police is made in Seki City Japan.
However, if what you want is an edc knife, it's hard to beat the paramilitary 2. It's obviously substantially smaller than the military or police, but it's definitely not a small knife. More like a medium size knife with the ergos of a large knife. The compression lock is absolutely brilliant as well. If you're trying to soak up all that is spyderco, I think the para2 is THE spyderco.
With that said, my absolute favorite spyderco, and the knife that is considered by most spyderco fans to be the very best knife spyderco makes, is the Southard. It's not cheap, but in my opinion it is easily worth more than the cost of admission. It's made in Thaichung Taiwan (hint: spydercos most premium, high end models are made in Taichung), meaning the fit and finish is impeccable and easily on par with knives costing double it's price. The southard features a Ti frame lock, ball bearing pivot system with a flipper opening mechanism, and carpenter steels' cts-204p steel which is their version of the highly acclaimed bohler m390. All in all, high end handle materials, high end super steel, bearing system pivot tech, outstanding ergos and design thanks to Brad Southard, and world class construction and fit and finish thanks to the folks in Thaichung make for one of the very best production edc knives in existence.
