6mm birch ply by far the best in my experience, though if a home layout then traditional softwood frame and chipboard top will do. 

 Avoid 'hardwood' ply at all costs unless at least 9mm thick

Hi Paul. Horses for courses, different materials work for different folk. I used 9mm marine ply on Kingdbridge when I built the boards 27 years ago. Heavy and not suitable for a portable layout. Built upon 2"x1" formers with 1"x3" on the edges for rigidity.  More recently I've used the WMRC box construction sections method with 6mm ply for the top. See below:

Laser cut to size by a company in Dublin, very quick to build using a heat gun, smaller pieces easy to assemble, and reinforced joint by fibreglass webbing underneath using PVA instead of resin. Each board is 2ft x 5ft so fits in a car and lightweight so can be turned on their side for wiring, etc. I'm unable to crawl around under baseboards anymore. Very stable and will not warp or sag in time. Sealed with paint for stability from moisture. Takes track pins well.

I used 3mm closed cell foam to cover the entire board with a second layer under the track for ballast. This offers good sound insulation as ballast PVA will never come into contact with the ply baseboard creating a sound bridge. Have fun.

I tried MDF 30 years ago but found it unstable long term and it was a complete PITA as it would not take track pins. Not as good with damp cold air as plywood from a stability point of view.
