I personally would pick New Super Mario Bros it will be an amazing title, however if you havent played Metroid Prime it will be worth getting it will last you for ages. It comes down to what games you like, Metroid is excellent but not everyone will enjoy it, while NSMB is a game pretty much for everyone plus it has multiplayer!
I would try to get both from relatives or save some money
