You may notice the 8's blade has a slightly curved, "banana shape" to it because it was designed as a close quarter combat knife. The Journeyman, however, has a straighter edge because it was designed as a utility knife. Both look cool and are great knives but each is designed for a different purpose.
Between the two, if you are wanting an SD knife then you may want to select the cqc-8. If you are looking for an edc blade then I would suggest the Journeyman. Both will serve you well -- it just depends on how you want to use the knife.
