I'm just curious who everyone views as the best and worst actors and actresses from every soap they've watched.

For me:

As The World Turns:
Best Actor: Ben Hendrickson (Hal Munson)
Best Actress: Maura West (Carly Tenney)
Worst Actor: Roger Howarth (Paul Ryan)
Worst Actress: Eileen Fulton (Lisa, except for the medical malpractice storyline, when she was great)
