If selecting now,at their current ages then Barnard is the better option at 25.
If making a comparison from them at their prime - different teams,different era so always a spurious measure - then it should be borne in mind that Ormerod was a freescoring striker at our present level which earnt him a move to the Prem.
Ormerod did well for us at that level,and made a significant contribution to 2002/3 season etc.
Ormerod would get my vote for which one whilst at their peak,but Barnard may of course go on to change that view next season.
