Acekard 2 Question

I bought the acekard 2 for my DS Lite.But i just found out that acekard 2i works with the DS Lite.So is the acekard 2i better then the acekard 2,or are they exactly the same?

I think the acekard 2i is a better quality build, just because it's newer. But they run games the same, they use the same firmware.

The design quality of the cartridge shell is better than a Acekard 2 because the casing is glued together instead of being attached or screwed. That's all really.
