The best 3D touch feature is the trackpad keyboard. It&#x27;s also very not discoverable (who thinks to force touch the keyboard?)<p>Having said that, 3D touch is far from the only improvement on the 6S. If it didn&#x27;t have 3D touch I&#x27;d still recommend the extra $100 to get MUCH better internals (processor, cameras, touch ID sensor) and a stronger body too.
