Reply to Traktor S4 vs. Pioneer DDJ Ergo (Serato)

Hi everyone,

I'm really wondering which of the 2 controllers would be better for me, as I am a completely new in digital mixing, so I have no idea what should I choose.
An important aspect would be that I'm a house-music DJ and I'm used to the Pioneer interface (I used to own 2xCDJ 1000mk3 and a DJM 800).
I know the S4 is said to be a better controller, but it's also pretty expensive, so I'd like to know if it's worth buying it.
A last note: DDJ Ergo comes with VirtualDJ LE Edition, but there's going to be a dedicated Serato software for this controller.
I'm really looking forward to listening your opinion, guys.

Best Wishes,
Cezarel
