The badger does fine if you want the smooth airbrush finish and need to spray large areas for primer or color coats. It can do medium size details reasonably well. The Iwata does the same but is also much, much better at small details and fine lines. The Iwata is also easier to use, disassemble, and clean than the Badger.
If you are committed to the airbrush thing I highly recommend going straight to the Iwata. My first thought when I started using it was "fuck I wasted years using that Badger!" but the Badger is still a decent airbrush.
For ref, the pic related is what I like the Iwata for. The fine preshading patterns are really easy with it. I freehanded the camo pattern with it as well, which I would not have trusted the badger to do.
