The Spydercos will be fantastic slicers. The Benchmades, because of their thick grinds will not slice very well, but they were not designed for that task. Spyderco has better quality control, but when Benchmade is on, they are good (I have a box of Benchmades). The Spydercos have bomb proof locks. If you use a knife rather than carry and play with a knife, the Spydercos will be the most satisfying.
