Tile is basically better than underfloor heating in terms of heat permeability and heat distribution.

Laminate (wood + impact sound insulation) certainly insulates against heat. It doesn't do much (necessarily). Most say they don't notice a difference. Some say it also doesn't insulate, it just delays heat transfer, meaning the laminate will be even more sluggish with temperature changes. Personally, I think there is less heat gain in the long run, even if it's only 0.5°.
