It seems appropriate to mention that HockeyFights.com did a small interview with McGrattan to list his five top fighters currently in the NHL (link:

These are McGrattan's top 5:
1. Patrick Bordeleau
2. Luke Gazdic
3. Colton Orr
4. Matt Carkner
5. Jay Rosehill
His criteria was simply on fighting technique/ability, not on wins and losses.
