plywood resists cracking, breaking, shrinkage, twisting and warping. Unlike melamine which is cheap pressboard and if you ever used pressboard and try screwing a nail in it then you know what happens, it strips because all melamine is just wood shavings pressed together and glued with a melamine coating.
Overtime the melamine rack WILL droop and sag if not totaly collapse because melamine is very sensitive to dampness (ball pythons need high humidity).
