I own both and love both. My top EDC knives are Benchmade mini reflex 2550, Benchmade Osborn 944, Spyderco Sage 1, spyderco caly 3.5. I will say this though. Spyderco knives come from factory always sharp where as some benchmades I had to sharpen because they edge sucked. I will say that the mini reflex 2550 has always been crazy sharp because I bought two and they both came sharp as well. Both companies have a lot to offer the knife community. Saying one is better then the other is just flat out stupid and shows someones total lack of experience with both. I will also throw Kershaw in the mix. One of my other favorite EDC knives are Kershaw scalion and kershaw leek. I just bought a Zero Tolerence 0550 and I am blown away with this knife. I consider Spyderco, Benchmade, Kershaw on the same par and all 3 produce killer knives that are meant for the same demographic. If you want to move up the food chain then you get into Chris Reeve, Rick Hinderer, Strider and a few others. These are amazing knives as well but you are going to pay a hell of a lot more money. If you got the cash why not? I owned a Chris Reeve Sebenza and a strider SNG at one time and sold them both. I just couldn't see the justification in price for the value. some people do but I didn't. Just my opinion folks.
