Captain Phasma vs Brienne of Tarth?

For those who don't know, Gwendoline Christie, who plays Brienne of Tarth in Game of Thrones also played Captain Phasma in Star Wars - The Force Awakens. Phasma was woefully underutilized in the movie so hoping they develop her character more in The Last Jedi.

Wondering what they would look like if they met. Who would win a fight?
