For me, two stand out: Jason Knight's Blade Show Bowie and Mike Ruth, Jr.'s Fire Stag Bowie. Very close, but in the end I favor Jason's Knight Blade Show Bowie. Personally, I am just not a fan of S-guards, however Mike's here s one my favorite ones that I have ever seen. Really nicely done! But what put Jason's knife over the top to me were the blade shape and the shape of the stag handle - I suspect it would fill my hand better.
Congrats to all of these makers. And thanks to Roger for doing this.
