I don't have tons and tons of Busse steel, but I like the S5 a good bit. It's not my favorite blade, but it's a nice little knife. I like others, like the scrap muk, more, but the muk isn't as versatile as the s5, so the s5 might get carried more often. If you got rid of the square choil, the s5 would be dang near perfect. And the edge holding of SR101 is a no-brainer on a knife this size.
