Which is the better game? I've got enough points for one game and Centipede caught my eye, but I don't know if Millipede is a better game.

Centipede is vertical, Millipede is horizontal.  Personally I prefer Centipede but try both out and choose for yourself.

Millipede adds some small elements to the game that make it more enjoyable, I find.

Generally, I prefer Centipede.  Also, you should keep in mind that the Centipede being offered is the higher quality original arcade version and the Millipede is the poor Atari 2600 port.

I bought Centipede and think it was a good choice.  Also arcade port > 2600 port.

I ended up buying Centipede, thanks for the insight guys.

You know what? I don't like Centipede or Millipede and I'm not sure why people love either.
