Reply to Kontrol S4 or Xone 42 + 2 Kontrol X1's?

Dear DJ TechToolers!

Hi I'm Wesley, and I'm not new to this community , I just never registered an account. Love this website though, very informative !

Anyway, I'm about to give my DJ-booth a refreshment but I'm believeing about 2 options for a few months already. I've saved up enough to get me new stuff in 2 weeks, but I'm just not sure what to get.
The options are a Traktor Kontrol S4, or an Audio 10 DJ + Xone 42 + 2 Kontrol X1's.
What I'm seeking for, is portability, flexibility and the ability to play timecode or with 4 decks.
I know these 2 options have all of this.

The S4 gets my attention because of it's portability, and that (almost?) every function can be controlled with the controller. Also support for timecode is very useful. A downside of the controller is that it doesn't work as a standalone mixer, because I often play my old vinyl (for scratching/mixing).

The Xone 42 + X1's gets my attention because of its flexibility and the good sound quality of the Xone (and adorable filter!).
This setup is also portable because you only have to get 2 X1's and an Audio 10 DJ with you if there's already a 4-channel mixer at the gig.
Flexibility = the ability to easily replace/add a controller (whenever there's a better one coming out, ''Kontrol X2?'')

Anyway, this problem is driving me crazy and I hope there are people here who can make things clearer for me haha.
And oh for what it's worth, I'm playing Techno/Tech-House .

Thanks!
