I'd just go by the numbers, you can decide really fast. Have em display
VPIP/PFR/AF(postflop)/nr.of hand

You can see at first glance what kind of player you are dealing with, and the amount of hands can tell you how accurate it is. (<50 hands it means very little)

AF (aggression factor) is the ratio of times that player has bet/raised compared to how often he has called. If a low AF player bets it's probably because he has it, if a high AF player bets it's more likely to be a semi-bluff or bluff or thin value bet because he bets/raises a lot.
