I don't really think you could go wrong with either one. I would just get whichever blade style that you think would work better for your edc cutting tasks. Sorry, I don't have any pics comparing the minis. But here is a full size 8 and 15 (with a Krein Regrind). Hopefully it can give you some idea of the differences.
