Don't know what kind of good you mean by good? Artistic achievement? Physical fitness? Or simply to shine in front of your buddies. Or simply a craft.
In terms of artistic achievement. I don't follow ballet very closely. But I think ballet is a little more accomplished than street dance, but it's also a little harder to achieve. You have to work hard from the age of 7 or 8 to the age of 27 or 28, constantly improving and working hard. Comparatively speaking, street dance is better to reach, but of course only relatively speaking.
From the aspect of physical health, street dance is actually relatively to other kinds of dance. It may not be very good, of course, when you are young, the body is generally full of vigor, but when you get old, it will highlight a lot of disease. Because street dance is more likely to receive accidental injuries than other dance types.
Ballet this kind of dance. I have a schoolmate said. Her teacher is sixty-seven years old. Legs say up to the shoulders and up to the shoulders.
From the remaining aspects, street dance is better. Because handsome ah ~
Want to make money with street dance is also faster than ballet and other classical dance
