Lighter, yes. Not stronger in the absolute, but stronger per weight.
Under a bending load, the outer surfaces take proportionally more
strain than the inner ones, which is the reason why I-beams are
I-beams.
However, I may be drilling holes in arbitrary locations and having a
solid core makes *that* connection more solid. Also, putting a 200-lb
drill press on a hollow core table top results in visible deflection.
With composite materials, probably some creep over time, as well.

The one I'm comparing to was constructed for me by a PLUG subscriber,
Dale Victor, when he was still working in Portland. Being a
professional woodworker, he had access to professional machinery and
was/is an ARTIST/CRAFTSMAN of Grade A, Number 1, Super Plus Plus
magnitude.
With a good planer, I imagine you could take a stack of relatively
straight fir 2x4s, square them up and get a decent, strong, solid wood
tabletop core. The veneer thicknesses on these older things (doors
and table tops from yesteryear, when stuff was built to last forever)
is a lot greater (like 1/8 or 1/4 inch) than the 10, 20, or 30 mil
thicknesses you can find these days.
