Somewhere along the line I recall hearing that plywood, while stiffer and lighter than MDF, tended to give more of a 'bounce' rather than absorb the impact and/or vibrations, which might not be desirable on a workbench top.
Any truth to this from y'alls experience?
TIA,

Don't know about that, but it becomes a moot point if you properly brace the benchtop. For a benchtop, the span from front to back is so small and if you brace it every two feet to support it along its length, any bounce is so negligible that you'll never experience it. MDF is not going to absorb any amount of impact or vibrations that you'll benefit from. Except of course, when it breaks...
MDF, but seal it with 3 or 4 coats of poly before using it.
