Need help choosing VC game FAST! (like now)

[Slash]

Ok I got 600 points and I'm planning on buying my first VC game.

So it's a NES game and I know that it will be one of these three(please don't offer any other game then the 3 i'm contemplating about):

Kirby Adventure 

Super Mario Bros.

Super Mario Bros. 3

 

Help! They are all so good... I think I played Kirby the most back in the day but damn it's a though choice.. 

Which is better the first mario (revolutionary) or bros 3 (epicer/more gameplay mario but less secrets?

Argh! Think I'll buy super mario bros 3... in 5 min if I don't hear anything soon!
Please hurry if you think I'm making a big mistake!
