Presumably as both the HSH and tiltrotor are demonstrators, the operational products will be larger?
I would rephrase it as -- both of these are technology demonstrators that are not appropriately sized for adequate utility or attack helicopter use. If either or both of these technology demonstrator configurations are pursued for development into those roles, they would inevitably be larger.
"The operational products" makes it sound like it is guaranteed that one or both of them is set in stone to be developed into an operational product. It's likely, but not definite.
What's the play here? Compound coax for scout/light attack(S-97) presumably for the Army? and tiltrotor for naval and Marine transport(MV-75 and V-22)? Potentially that quad-tiltrotor for the Army as well if they decide to procure it? I guess all that's really left in terms of capability for Chinese helicopters would be basically the AHL project which seems to be in some sort of limbo.
There's no particular play.
These are both new and fairly exotic next gen propulsion arrangements for next gen rotorcraft. It makes sense to develop technology demonstrators of an appropriate size (and with sufficiently available powerplants) to verify their configurations as part overall next gen rotorcraft efforts, likely with an eye that one or both of them could have applications for next gen utility and attack rotorcraft.
