I prefer satin finish for my blades. It looks good and has better corrosion resistance compared to bead blast. Blade coatings are second, mainly for corrosion resistance. The salt air where I work isn't the best on an EDC.
I'd list mirror finish at a distant third over mirror finish close behind it. Mirror finishes don't really look that good to me, and get messed up easy, but are better for corrosion resistance. Bead blast looks a little better and are easier to fix, but the corrosion resistance sucks. I have one bead blasted blade in ATS-34 that will rust in about 3 days of EDC duty even if I clean it up and wipe it with tuff-cloth... it still looks better after cleaning up than a mirror polished blade does though... so bead blast gets the 3rd place spot.
