Chipboard is a particle panel with a film on top. Cheapest of the three, holds its shape, fears water at the edges. That is why edges near the sink get two-millimetre banding, not nought point four.
MDF is denser and takes a router — curved and milled fronts are made from it. It paints any colour but scratches more visibly.
Solid wood is wood. It lasts longest and is the only one of the three that reacts to humidity: in winter, next to radiators, gaps open on the panels and close again in summer. That is not a defect, that is wood.
