All in all, both Microsoft and Sony have clearly taken note of the shortfalls in their current-gen controllers and make amends without over-stepping the mark - inevitably arriving at a similar middle-point in ergonomic design. Microsoft is no stranger to the process of evolving its pad design with every generation, going from the mighty Duke on the original Xbox, to a minimised S version which formed a basis for the more streamlined 360 pad. The Xbox One continues that tradition of refinement with gentle tweaks across the board - plus the addition of rumble features which make a surprising difference - though the result is one that should be warmly familiar to existing Xbox fans.
Meanwhile, Sony's DualShock 4 shows a more radical departure from the Dual Shock form factor it's held onto for the last three generations. With the revelation that neither the PlayStation 4 or Xbox One offer compatibility for current-gen pads, it's just as well that these new controllers bring enough incremental tweaks to every facet of their designs, each adding up to a broader sense of overall improvement than we'd expected going in. Certainly, controller comfort will always be a strict matter of personal taste, but between the two, the balance between conservation and evolution has been judged with care.
