Which 3D 6th gen games have aged the most gracefully visually in your view, and why

[curl-6]

Possibly a controversial take, but I feel like the Gamecube has weirdly aged better than the Xbox.

Xbox was more powerful, and games like Chronicles of Riddick, Doom 3, and Halo 2 were seriously impressive at the time, but in retrospect I feel like their early use of pixel shaders hasn't aged as gracefully as Gamecube's best looking titles.
