Nintendo DSi or 3DS?

[MommaTooters]

We are looking to get our 5 (almost 6) year old a Nintendo DS of some sort. No flames please! We just can't decide between the DSi or the 3DS...then add in the XL versions...oh may. Way too many choices.

I know many of you have bought one of these systems for your children about the same age so I thought I would come ask what your suggestions/recomendations are!

So tell me...DSi or 3DS (or other?)...
