My guess is they would both do well with 1 cuft and no heavy driver on one panel. Get to a certain point and the glued one would break apart while the screwed one would stay together but become increasingly deformed. oooh tilted parallelogram cabinets :-)
I've done some testing myself, and steel framed VCR's that frustrate you for days then won't play anymore fair very well on drop tests. You can't throw it high enough, requiring the use of simulated dropping technology(sledgehammer).
