You are witnessing the fill-boundedness of that chip. Chris's testing was on a G1. It has very different performance characteristics.
Canvas is software rendering using a special framebuffer blit which is lightning fast. GL is hardware rendering using a texel shader (even if you don't use it - it's there) and drawing to a framebuffer. Don't assume one will be faster than the other for all cases but do assume that the hardware gpu will probably always win when not testing straight fill-rates. If your test started skewing/scaling/rotating the quads, you'll probably see the gpu pull ahead. If you have to do hardware transformation of lots of verts, you'll definitely see the gpu win.
