MDF is more dimensionally stable, more uniform, stiffer, and better damped.
On top of that, it machines better and is a lot less expensive.
Void-free birch plywood is a good choice for braces and sub-woofer enclosures (it's even stiffer, and in a sub-woofer the resonances will be above the frequencies of interest).
