Completely disagree. Doing three finger swipe x times is just as fast if not faster than keyboard shortcuts that require you hunt down the window you're looking for.

It's objectively slower when you need to leave the keyboard with one hand to reach your touchpad. I'm thinking about a desktop environment here where 1. you might not even have a touchpad and 2. you have your both hands on the keyboard.

I mean maybe if you're using vim all the time, but most of my apps require mouse interface, so my hand is usually near the trackpad. Even when I'm using external monitors I still use the laptop keyboard and trackpad.

Good for you if it works, but it doesn't for me and I find it cumbersome.

I don’t think the literal fraction of a second difference matters.

It matters after a long day and it adds up. On top of the time lost, it's also a matter of ease of use.
