Choils can be hit or miss. I have had several that work great and some that don't work so well. I think something that is usually bad by everyone's account is a choil much larger than a sharpening choil but just too small for a finger to be comfortably fit for choking up on the blade. You get the worst of both worlds. Material can get caught in the choil stopping the cutting action, and you cant get any closer to the edge or fill the void with a finger.
