Plywood vs. HDF core for dimensional stability?

Hi all,
I would like to install an engineered bamboo at my beach condo, obviously a high humidity area. I've done a lot of google searching but it's not clear which would be a better choice for me- a plywood or HDF backing? Everything I find is very contradictory (the manufacturer says plywood is more dimensionally stable, but look at all the info I found on the internet below!!!). Does anyone have any thoughts or experiences with this? Thanks for your help!

Engineered Hardwood Flooring:What you Want to Know to Buy Smart!
Probably the best of the lot in that plywood is inherently the most stable because of its alternating layers of thin wood

What’s Hot in Hardwoods : HDF | Portland Oregon Flooring Store | Tigard Flooring Company | Area Floors
This HDF core is much denser then the plywood core commonly used in engineered wood and creates a very dent and moisture resistant real wood floor.

How Hardwood Flooring is Made
HDF is even more dimensionally stable than a plywood core board.
if the intended
area is prone to moisture, the core
material should be HDF board which
has better moisture resistant property

We have gone with plywood. I just have to believe that it is more stable than HDF.
