It depends on the game you're playing, penetration, spread, and how many indexes you're using. Walker's count (Hi-Lo Unbalanced) has better playing efficiency, so it performs better if you're using a smaller spread, playing all, sitting at third base, etc. Secret Monkey has better betting efficiency, so it works better with larger spreads, wonging, etc.
Generally speaking, they're pretty similar in terms of performance, and both work fine to get the money. I think Secret Monkey will work a little better for most people because it's a balanced count, and a lot of people are too lazy to learn full indexes.
