I use ws4s ,,,with backphone setup,,and also use the module with Vance headphones.
If you opt for ws4s,,,you have more options available for aftermarket.
Ws5s to me tone not high enough-- makes working in iron tougher,,at least for me...
Vance headphones--- provide great tone.
Ws4 provide almost as good a tone as Vance headphones.
Grey ghost Deus modified provide crappy tone for me.
So now you have my opinion on what I have owned and ran.
