I prefer dumbells as I feel it more in my pecs while the barbell press tends to overwork my front delts.

I also like the challenge of the dumbells. Once you get rather strong it becomes a task just to get them into position. Not everyone can kick-up the 120's into place but anyone can unrack a 300 pound barbell. Further to that point, how many guys can bench 250 on a barbell (plenty) but how many guys can safely handle 125 lb. dumbells (not nearly as many).

Also, strength imbalances become more apparent when training with dumbells. Barbells allow the stronger side to compensate somewhat for the weaker side. It is not as bad as when using machines but it still happens. With dumbells any differences become immediately apparent.

Great poll Steve
