Is that true the New Earth version of Bruce Wayne (Batman) is the most relevant version of the character?
Considering the fact that the original Earth Two and the Earth one versions were erased from history following the collapse of the original multiverse and because most of the most important stories featuring Bruce Wayne are part of the New Earth continuity compare to the Golden and Silver ages versions of the character.
Or maybe, it's the most relevant version of the character because both New Earth combined with Prime Earth make up the modern age version.
