I am also on the Presonus forum as good ol Starise. I have a Presonus interface and this is mainly why I ended up there. It isn't as happening of a place as here though.
I tried Studio One. I have no problems with it. I like the pro channel and GUI in Sonar much better. Studio One has a great audio engine in it.
You can make good music on either one. Didn't know there was a forum band on Presonus. I heard their company band though. Those guys are decent. Who would judge the competition? We would need someone totally unbiased....maybe we could get Rain. He uses Logic.
