Tecnica has at least a few models with this type of foam (Hiperfit) in their liners. (some of the Diablo's and some of the Vento's) It will heat mold plus take a compression mold of your foot. Nothing special but Hiperfit feels better than hotform. Tecnica markets its' "Hiperfit" material as their "top of the line" non Hotform liner material. Ultrafit falls (I think) next in line for the liner material. You'll probably see "Hotform" liners fall out of the North American line soon.
I'm looking into a Diablo Flame which comes only into Ultrafit or Hotform. So sounds like between the two and considering there is no Hiperfit Hot form is better, is that correct? Could you expand a bit on why you think Hotform is inferior?
The "Hotform" liners use a foam that has little to no elasticity when coupled up with their outer covering. Also, the "Hotform" heating assembly is made of a heavy cloth material with the wires sewn to them. This combination makes these areas very hard and unelastic.
