What is the difference between expensive and cheap golf balls?

Expensive Golf balls are nicer to hit, the feel softer and give more feel when you are putting and pitching. A major difference is they spin more so you can hold the green on approach and pitch shots, so this will improve your game. Cheaper golf balls are usually of poorer quality and feel quite hard when hit, they hardly spin at all and give you know feel at all when pitching and putting.
