Consensus? I'd doubt it. I think it will depend highly on what is important to individual players. For example, I know there is an older version that online DD players loved for the hitting mechanics (don't remember if it is 16 or 17). I imagine some guys would love the older version (12 or 13?) that last had the full broadcast presentation before they switched over to the broadcast version we have now.
I'm a "gameplay first" guy, so I tend to go with 19 because of the tremendous enhancements to the defensive animations - which built upon improvements made in earlier editions. It's incredibly likely I will go with 20 as my new "best" after it launches.
