Compared to clicking a button I would say a lot faster as you don't have to move your mouse to start initiating your gestures. It's maybe more marginal compared to a short key. Still your hand is already on the mouse ready to execute a gesture. Personally I find it really convenient and for me it's the second most useful add-on after ublock. When using a browser on other computers that don't have these I find it really tedious and I am shocked at how much ad there is.
