The question is in some cases, is it better? Plastic is not always better than wood or steel but a main reason for using plastic is that is relatively cheap, it is easy to shape using heat (depending on if it is a thermoplastic or a thermosetting plastic) So its more about for what you are you are making where plastic might be better to use, it is not always best. Like in the engine in a car, using plastic would be a dreadful idea because of all the explosions.
I think a steel garage is better than a wood garage because wood can rot and steel can't. Steel is a more reliable choice.
The better insulator is plastic because wood can get wet easily and stay wet longer than plastic.
Wood is a better conductor of heat than polystyrene. Polystyrene is a poor conductor of heat, making it a good insulator. Wood, on the other hand, conducts heat more efficiently due to its molecular structure.
Wood resonates much better than plastic or metal.
because wood is a natural item
Plastic generally floats better than wood due to its lower density. Density is the mass of a material per unit volume, and since plastic is less dense than wood, it displaces more water and floats more easily. However, the specific type of plastic or wood can also impact their respective buoyancy properties.
steel requires less maintenance because it will not rott as fast as wood without any protection added.....polycarbonate plastic is the future of pool walls.
Wood seats are generally stronger but I think plastic seats are more hygienic.

Two identical pieces of ice, each placed on identically sized and shaped blocks of plastic and wood at the same temperature, will melt at a rate proportional to the thermal conductivity and the thermal mass of the object they are on. Generally, wood is a better thermal insulator than plastic. Short answer: wood.
Plastic, wood and paper are insulators and very poor conductors of electricity.
