Better and user friendly gui library for java?

Question

which library or framework what would you like to name it, which one is better?
javaFX,
Swing.

Answer 1

'Better' is only an opinion ;)
As JavaFx was developed to improve the existing gui framework Swing, it should be better.
Although it really doesn't hurt to know them both, as many companies still use Swing and don't plan to move to JavaFx.
