The playstation intreprets a quad as 2 triangles. (I know this is true
because I've got the numbering wrong on a quad many times, and the GPU
renders 2 distinct triangles) Look at this rough sketch. (If it doesn't
look right, look at it with a fixed size font)

Because it does this, it really doesn't matter which you choose. If
there is a speed difference it will be minimal. However, the data for 2
triangles is larger than 1 quad. So if you are dealing with large
models, it may be more efficient to use quads rather than triangles.
