Barbel or dumbell shoulder press? Which is better for mass?

Yup, mix it up. The only reason the dbs are harder for you is because you're not used to them. Once you start doing them, you might find you can do more than with a bar.

Personally, I prefer dumbbells. For one, it eliminates the need for a spotter. Also, I think the increased range of motion is better for stimulating growth. With a barbell you can only bring it down to about your collar bones or the base of you neck(depending on if you're doing in front of or behind the neck) whereas with dumbbells you can bring them all the way down and really stretch and stress the delts. Ok, now for my rant. Bring the goddamn dumbbells all the way down until they touch the outer head of your delts! No more of this partial range of motion bullshit! Ok, I feel better. I just see too many people doing half-2/3 reps and I get pissed off.
