Wyatt Earp from Tombstone or Rooster Cogburn? Who Would Win? [POLL]

Wyatt Earp was born this day in 1848.

This got me to thinking about legendary lawmen, which got me to thinking about lawmen in movies, which led to me to thinking about Tombstone and Rooster Cogburn. 

So....now my little imaginary mind is wondering what would happen in the main characters from those movies went head to head in a gunfight.  Would Wyatt Earp played by Kurt Russell win? (with no help from Doc Holliday, of course).  Or would Rooster Cogburn played by John Wayne win?

Let us know what you think.
