Favorite version of a game (other than the arcade version)?

[OldSchoolGamer]

So, I was thinking, we love and cherish so many classic arcade games. However, often our first experience with a specific title isn't with the original arcade version either becuase we were to young or simply never came across the arcade original. Because of this I would love to know WHAT IS YOUR FAVORITE VERSION OF AN ARCADE GAME OTHER THAN THE ORIGINAL?

Answers can include ports, console versions, computer versions, PD, shareware, web browser flash game, hand held, portable, game & watch etc.

For the record, I ask this as over the years I have discovered many great games that I enjoyed more then the arcade original and am always interested to play a good version I might have missed.
