Depending on what you expect from a bot, nobody but yourself can state which bot is the best
Give a try to Killaruna's Parabot too (

Given your config the bot should be running (plugin #7). Try typing "HPB_Bot addbot" in the server console (beware of the capital letters). This should add bots to the game. Also, make sure you have waypoints for the map you want to add bots into.
