I think the advantage makes up for your disadvantage. The reaosn being that you know what they're doing, and they don't know that you know. It's a bit like multiple-level thinking, and you're one level ahead of your opponents.

You know what they're doing, but you don't know why they're doing it because you don't know either of their cards. For example, the player whose cards are seen raises on the button preflop. The cheater is in the SB and reraises. You are in the BB with AJ. What do you do? One possibility is the button was making a steal attempt and the SB knew this and knew his otherwise marginal hand had him dominated. Your AJ could easily be the best hand. But another possibility is that the button had a strong hand and the SB had a monster. Your AJ could be dominated by one or even both. So even though you know what the SB is doing, since you don't know why, I don't see it as being a big enough advantage to make up the disadvantage.

Maybe this example is too contrived, but I think it will usually be the case that you see what the cheater is doing, but you don't know whether it's in reaction to the other player being strong or weak, bluffing or value betting, or whatever the scenario might be.
