Personally, I'm a barbell guy. I used to use dumbbells for everything but progression and growth were slow, got turned on to barbells and progression and growth are constantly improving.
Just my experience, the pro's to barbells are more weight and more muscles used. Because of that I can always get 5-10 more lbs out of my compounds on a consistent basis.
Whenever I use dumbbells it's to hit a specific area, but I'm not a bodybuilder nor a guy who is large enough to have specific areas that are lagging, so I don't use them too often.
I guess it depends on what your goals are.
Short term Goals for 2013: Hit 900lbs combined at a meet competing in the 181lbs division. Then hit 1,000 combined in the gym by New Years.
