Reply to Ableton or Traktor??

So, I just got rid of my old DJ gear and I have been watching a lot of videos on the midi fighter and Traktor Kontrol S2. I want to be able to mix live, but also be able to produce live? And I was wondering do they make sound packs for Traktor too? Or am I better off going with Ableton? I want to get an S2 and Midi Fighter, but I am more intrigued by producing live. So should just get a couple of Midi Fighters and drop the S2? I need help!!! This is a really hard decision. I don't want to make a big purchase and then regret it in the end. Thanks guys.
