9 trophies to Wilkinson v 13 for Sexton (dismissing second rate or secondary ones like the challenge cup, powergen, triple crown and one off games) and both world player of the year once, Sexton the better Lion and marginally has the better record v NZ whereas Wilkinson has the higher international win record. Both were key players in any team they played for for most of their careers too (although Toulon continued to win without JW, Leinster went to **** without JS)
You're either massively overrating a world cup or massively underrating England's world cup winning team to dismiss this as a conversation so flippantly.
