Having used Vive, Index and Quest I've had most trouble doing gestures with Index. Doing facial expressions was easiest with Vive as you just slide your thumb around the rings making combinations and quick switching straightforward and doing hand gestures was easiest with Quest as you just do the gesture but the controller is very discrete about which buttons you're pressing or touching. 

Index allows the most options but still feels clunky to use as it doesn't give proper feedback from your grip fingers, you literally can't do the neutral cupped hand and have to fuck around with the finger bones to make them look less jank.
