Reply to Mixtrack Pro II vs. Kontrol S2

Hi, I'm sorry to start up a familiar debate (I've been researching the community for the past day), but does anyone know the MAIN differences between a Mixtrack Pro II and a Traktor Kontrol S2?

Can you play samples on the S2 like the drumpad on the Mixtrack Pro?

If I'm not mistaken, you can map Traktor fine to the Mixtrack Pro, right?

Thanks a lot!
