Little Ronnie looks better, but you'd have to be a moron to pretend not to realise that Ronnie's added width and overall size was what helped him stay on top. If he'd stayed all streamlined then the Jays, Levrone's etc would have dwarfed him after a while with their superior width and thickness.
Jay in 2003 especially would have beaten Ronnie 2002. I think this was where Ronnie was clever, spotting Jay's strengths (delts and quads) he went out and arrived onstage in 2003 with the craziest delts and quads seen in many years. Suddenly Jay's trump cards looked entirely underwhelming.
It's like how old school Jay looks better than 2006 Jay, but you can't blame the guy for doing what it takes to win the O.
