They're all about the same, and I really don't like any of them until about the 20th fish, then I'm glad for the assist. I have a Rapala deluxe electric filet knife that I currently use. I like it because it has a 110 adapter, and a 12V connector. That lets me use it on the Mule, or at the house. It was around $60.
I still use my old filet knife to cut the ribs out.
