Best Keyboard Layout? Qwerty or Dvorak?

never used dvorak , i don't even know what is it ... qwerty prefered

qwerty of course, familiar to all, though rather strange, still don't understand her.

Qwerty is obviously the superior race, but that's really bias because it's just the fact I'm so used to it and I have the whole keyboard memorized from micrometer to nanometer.
