The styles do, because of how they are arranged..
But where it comes to right hand voices, i personally think yamaha is in a league of its own for many of them.. whilethe ketron voices have a great characteristic... they are much much more straightforward then the yamaha voices..

Trough the depth of many of the sounds they all require effort and a different playstyle.. but as you learn how all the articulations work in your advantage and how to trigger them.. its just so much more realistic then korg or ketron..

Also need to say,that sometimes i am struggling to get it right, like with some of the acoustic sa guitar voices.. it takes effort to find a way to play them softly yet fast... sometimes you wish, you could kill the intrigueing articulations and just play them straightforward..

Ketron sounds are simpler, and they might have more pressence, but certainly are not as realistic as yamies..
