First, I would strongly suggest waiting to buy MP3 and just get the Metroid Prime Trilogy that is coming out mid-August. It will have MP1, MP2, and MP3 all with 480p, widescreen, and wiimote controls for normal price which is just spectacular!!
Second, the two games are very different so its really what game style you are looking for. I don't own Little King's Story yet but it seems very fun, long, and RTS oriented. I do own Punch-Out and while it is a fun little romp, it is pretty short and straight forward. If I could only get one I would get LKS just because it is more game for the money in my opinion.
* didn't realize LKS might be hard to find so I am going to go grab it today or tomorrow ;) thanks for the heads up!
