With no information on the model of club they are, I would say that TaylorMade is known for their clubs while Cleveland is known for making the best wedges. Take it for what it is worth, but I would go for the TaylorMade irons.
General rule of thumb though might not apply here and all situations: For the most part Taylor Made irons generally lead toward the player improvement variety while Clevelend Irons will be better suited if you already cary a lower handicap.
