Yes, I also recommend to follow the Phillip's link. Off hand, however, there are two obvious differences between the two. First is the size. The Voyager is larger than the Delica, and how that factors in is up to your preference. Also, the serrations are different. The Voyager has a Ginsu-styled alternating serration that can't be sharpened. The entire blade has to be sharpened like a plain-edge. And once the serrations are gone, it's gone. Spyderco's serrations are larger and can be sharpened. To side-step a rather controversial issue, I really can't say which serration style is better. In my personal experience, both have been proven performers and ultimately makes no real world difference which you take. In my personal opinion though, if it has to be serrated, I prefer ones where I can sharpen the teeth. But that's just me.
