What's the most technically impressive DS game? (Day 15) + Dreamcast final

Board 8

I have to think about this one. Hunters was very impressive but is early on. That Wizard of Oz game looks crazy, basically like a 3DS game. My instinct is to say Kingdom Hearts 358/2 Days for similar reasons to Chain of Memories. It had multiple FMV cutscenes, this time with full VO, and the 3D graphics and sound were very impressive for the system. If I remember correctly they had an extra large cart just for that game. However, I never played or even saw much of Re:Coded, is that more impressive than Days is?
I just decided to change this sig.
