Respectfully, BigJim, your overwrought and somewhat didactic response belongs in PracTac, not here. This is the blade discussion forum. It is not the domain of tactics, law, or criminal statistics, and those are outside the scope of the original question anyway.
Jinuineasn has made it very clear that he cannot carry a firearm, so I find it humorous that individuals are always so ardent in recommending them in threads like these. I can't carry one either, due to where I live. We don't know what sort of training Jinuineasn may have or any other details. We do know that folders with blades over four inches are legal where he lives.
Given the info we have, I recommend neither as best. I crown the Spyderco Ronin as the best SD knife the company offers. It is easily concealable, comfortable to carry, and very ergonomic. It offers tremendous cutting power, particularly in slashes. Further, it can also stab satisfactorily, a deficiency the Civilian has. Part of the Ronin's virtue lies in it being a fixed blade, which provides for the fastest most reliable deployment. On a related note, the new Street Beat knife has many similar characteristics to the Ronin, and may be a good alternative. I don't own one, so I can't say.
If fixed blades are illegal, my next recommendation would be the Yojimbo. It was developed to very closely mirror the Ronin, and it absolutely does. Its cutting performance is equal, and the slighly larger handle of the knife is in some ways better. The linered G10 of the handles and compression lock also make the folder very durable, but when you're talking Spydercos of this price point and classification, that's a moot point.
