Shoulder to shoulder is good
I'm always trying to get my buddy beside me and making the eye contact with OK signal
I suggest beside me, however I explain that I have good perferial vision and situational awareness but I get po'ed when I have to hunt for my buddy. As long as they are reasonably close and within my vision I'm happy. I don't mind excursions out of my vision as long as I know what's going on, I'm in no rush to get back to the surface.
Normally I'm solo or same ocean buddy, so when I dive with a buddy, I'd like a buddy dive.
From my limited experience, real newbees have been very good, but ones with a some dives under their belt not so much. A non scientific sample to say the least, and my experience may have to do more with the divers willingness to learn than their dive count.
