Diagonal placement geometrically eliminates early sidewall reflections, which imo is highly desirable. And assuming the room isn't overdamped, the energy which normally would have been in those early reflections survives to become beneficial later reflections.
In a square room, I'd suggest setting up not exactly along the diagonal, but rather rotated a few degrees. This way the woofers will each be a different distance from the room boundaries in the horizontal plane, which should improve the in-room bass smoothness a bit.
