I have a Techno and two Dragonfly 2s. I think the DF2 is probably one of the most refined(as in CQI'd) designs that Spyderco has, but the Techno is one of the best collab designs. They're both amazing at what they do. The DF2 is a better slicer, the Techno is clearly beefier, and, for what it's worth, has a higher fidget factor. The DF2 is perfect in-hand, and that's true for most people. The Techno is a love/hate thing for many, but for me I loved it the first time I held it. I think you need to go find one in person and hold it, and decide if it works for you. If so, it's a great knife to have, and definitely is a bit more upscale than the DF2. I also have the Chaparral which someone mentioned(though it's the CF original), and it's a fantastic knife.
All in all, I think the Techno is my favorite knife that I own, but the Dragonflies are probably the best knives.
