I havn't really noticed any significant change in speed. It also works well in tandem with LMT which can set up a pie launcher to get to favorite apps quickly. In addtion I would recommend GMD which allows you to set up gestures to get around system. For example I've set up GMD such that double tap removes or brings back status bar on top of screen. Also swipe with two fingers to right brings back previous app and so forth. Gesture designs can be customized in many ways. It's fun to tinker with.
