I've honestly made the best gains in the past year through the 3 day DC split. I'm just speaking from my personal experience, but having to go balls out 3 days a week, and not having to focus on bodybuilding (other than getting your meals in) has been great for my body and mind (chronic-neuroticism).
I've gone weeks without ever giving my workouts a second thought, as long as my weights or reps were going up, and I was getting 6 meals in. And people who saw me months later were shocked at how much size I gained (completely natural).
So definitely try out different routines to find what works best for you, but don't give up on DC just yet.
