Which is the best type of wood for kitchen and bath cabinets? Plywood or lumber core?

I have seen some cabinets made using lumber core plywood where the edges were left exposed, sanded and stained. It looks okay but I reall don't like the look.Which is the best type of wood for kitchen and bath cabinets? Plywood or lumber core?
