Which acting performance is better??and why? ?

Javier Bardem for me because he played one of the most frightening characters ever on film and barely spoke a word. You might say so did Arnold Shwarzenegger in Terminator, but he was scary looking and could barely speak english at the time that film was made. Bardem is a really nice guy if you've seen him in interviews and other films and he speaks just fine. I had nightmares after watching that film and that hadn't happened to me in years.
