I think I get it. The racket's a little bit different and the shuttlecock looks a little heavier and is called a Speeder, which is nice for those with delicate sensibilities. You don't want Maria Sharapova saying the word "shuttlecock" over and over. Beyond that...

I'll tell you though. I think they might be onto something with this Blackminton stuff:

Blackminton's basically Speedminton with black lights and ridiculous glow-in-the-dark makeup. If there's something that isn't improved tenfold by the addition of black lights and ridiculous glow-in-the-dark makeup, then I have yet to find it.
