Swing was by far my favorite.

Nice. My team constantly gripes about it but I’m all, “…it’s a well designed UI toolkit…?” I can make it do anything. It took me weeks (as a newbie) to try to lay out UI components just so with the new hotness and at the end I had to give up and move on. It would’ve taken me five minutes to do it with Swing.

As an engineer, Swing is great! Granted, I wouldn’t use it to deliver a polished UI to users.
