I love all forms of dance since it is an expression of our inner selves which can have many shades or even extremes. Out of the above, I'd choose salsa, ballroom, folk and bhangra. It can change with my mood. My other favorites are ballet, kathak, bharathnatyam and many forms of Indian dance. I think kuchipudi is one among them, I'm not sure. Its an expression of emotions so every form is extremely beautiful.
