Reply to Kontrol S2 vs. Denon MC3000 vs. AA VMS4.1

Hey guys, new to the community here and wondering if any of you can help me out
I'm looking around for a controller upgrade and the 3 that it's pretty much come down to for me is the:
-Traktor Kontrol S2
-Denon DJ MC3000
-American Audio VMS4.1

But beyond that I'm stuck, I keep leaning towards one.. then back to another.. and so on
Some things about me.. I currently have a shitty Pyle-Pro controller, it was basically the cheapest thing I could find on the internet lol. I'm looking to step up to a more professional controller for parties, small clubs, and bar gigs. I just recently purchased Traktor Pro 2 so I've got the software, and assume all 3 are equally priced.

Which controller would you suggest? What are some pros/cons etc?

Thanks in advance!
