I have both American Angler and Rapala corded knives. Both are 15+ years old and going strong. Have had the Bubba Li-on cordless for about six months now. It is convenient in that I don't have to be near a power source to use it. Does good for smaller fish but doesn't have the horsepower as the corded models. For a modest amount of fish I use the cordless for the convenience but if doing a cooler full corded is much faster, for me at least.
