Quads also have all the advantages that loops enjoy over dipoles. One
thing that comes to mind is a marked reduction in static electricity due
to wind and snow because the entire loop is virtually at DC ground.

That's what I thought too, I built the quads using insulated wire in hope to
eliminate atmospheric static, but I could barely tell the difference. What made
huge difference (wiping out static completely) is the use of stacked antennas,
or having larger antenna over the one in use. The top one would be 20 over S9
while lower one is dead silent.

Quad advantages: made of wire, no corroded junctions like with Al tubing. Quads
rule up to about 5 el. then Yagis take over. I have 3 el. design that is 50
ohms, no matching, broad band. One advantage quad has that it is only antenna
that can be used for different polarizations with the same hardware. Parasitic
loop doesn't know what polarization it is.
