Are ivory keys better than plastic keys?
This is mainly a matter of personal taste. Real ivory is porous and gives the pianist more grip. Plastic is more slippery. So depending on what you like determines which is better for you. I believe that people tend to prefer the key top material with which they grew up. Ivory has long been the traditional key covering material, and a piano with a perfect set of ivory is probably worth more than the same piano with plastic. But an instrument with many chipped, missing or broken ivories is probably going to be worth less than the same instrument with plastic.
