Which would you buy and why

4Trak and simple answer:
The S4 is a cheaply made thing and has a soundcard that does not even come close to some 200 bucks controllers out there and is 100% plastic.

The 4Trak is A TANK, build quality is out of the roof, it is intuitive, it has great jogs that are tightly matched to traktor. So if you want the best Traktor controller with the best build quality and a standard use layout the 4Trak is your buddy. No part of the S4 comes even close.

If you are on a budget, then both choices are bad. The one is a highend controller and the other want’s to be one.
Just because someone sells it cheap smells funny and if he has an honest reason it is because the S4 is not worth that money…

If you are on a really tight budget but can spend 800? That does not match.
In all honesty:
Get a digital jockey 3 (if you want Traktor so badly) and add an F1 (which will contain the Pro license) and you are still cheaper than the above suggestions. Can do almost anything and have spare budget to buy really good headphones and decent monitors.

You cannot demo Serato (Itch) as it will only work with a certified controller. If you just start it without a controller it will start in library mode, which will only allow you to sort tracks.
