......maybe my "foam is difficult to work with" comment was a mistake.

But I do like plastic honeycomb core a lot better than sheet foam, in
general,
for a variety of reasons. Substantially better compression strength
and durability is one such reason. Honeycomb core is easier to dovetail
together too, in order to make extra-wide or extra-long panels, prior
to
the actual layup.

For panels used to make seat tops and/or dory bottom panels,
an equivalent amount of fabric and resin, applied over honeycomb core,
makes a stiffer, stronger panel than the same layup applied over foam.
.......in my experience anyway. I'd call it better stuff.
