Been using Magnus Stingers and Buzzcuts for years. They both work equally well but I like the Buzzcuts best. The animals I shoot don’t go far. I only take high percentage shots. I use a Stay Sharp sharpener and get the scary sharp.
Based on the interaction of how cutting works, I would conjecture that a straight edge is better overall VS. serrated. An interrupted cut would add higher pressure spots on a blades edge. Not saying serrated doesn't work. Sharpening the serration would also be more difficult
I have some serrated blades but I have not repurchased any of them either.
