I haven’t used Samsung’s BD players, but I believe the higher end models have Netflix, Amazon VOD and VUDU support. FWIW, I wouldn’t write of Vizio’s hardware; they offer a compelling feature set at a very competitive price point.
If you have a Sam’s Club or Costco membership they both offer a 90 day return policy on electronics so there’s an easy/low risk way to try out the player that catches your eye.
