Everyone has a favorite and just every one you ask will give you a different answer. In reality I have found most grubs or jerkbaits 3 to 5 inches will catch you a snapper/squire, though some do work better then other on different days, times etc etc. Try some thing like a gulp 4" swimming mullet in pumpkin seed or a 5" jerk shad in Limetiger for starters.
