this is such a bad comparison, gyro is a nice option for those who want to use it but it will never be better than stick aiming in a competitive shooter. Moving both your wrists to move a controller is just less precise and slower than moving a stick with one thumb.
That's the thing about gyro aim, at least the sort being discussed/requested in this thread.
It literally
is stick aiming - but with an extra layer of mouse-like fine aim control tacked on. It is by nature faster and more precise than sticks alone.
See, if you were talking about Wii-era pointer controls, I'd be right there with you, even if I'd probably meet some resistance from folks who loved that style of control.
Gyro aim quite simply isn't that, though. It's like you're holding an air-mouse that lets you make precise and immediate adjustments to your stick aim. It feels just like using a mouse because it operates on the same principles - immediate, consistent 1:1 motion->response, rather than how sticks work, where you're adjusting the velocity of your camera movement.
Think of it like this - imagine using dual analog sticks alone, vs. using dual sticks PLUS you've got a third arm holding a low-sensitivity mouse.
That mouse you're holding in your third hand - you're not going to be using that to turn your camera facing. That's what the sticks are for. Except now you've got freedom to crank up your right stick sensitivity, so that you can make quick changes to your camera facing at any time - without sacrificing fine aim control, because your third hand can just use the mouse its holding to line up that cursor with ease.
That's what gyro aim is, and it's awesome. I've played a lot of shooters over the years and the only reason I generally refuse to play them on consoles these days (outside of cases where M/KB is supported) is because gyro aim hasn't been adopted as a standard yet. Sticks alone just feels cumbersome and limiting now that I'm used to its alternatives.

That said, I def understand why someone would find it unintuitive on paper. Moving your controller is something that you're already doing unconsciously every time you use it. Even just tweaking your grip'll do it. That said, gyro control is neither as cumbersome or as prone to interference caused by natural motion as one might assume. It actually feels very natural after just a little while of using it. Not to mention the fact that most well-implemented gyro control setups have inbuilt software solutions for those issues that allow players to decide for themselves exactly when gyro aim is or isn't active.
I hope I've made a decent case for why well-implemented gyro is innately faster and more precise than just using a stick. To me, it just makes intuitive sense that it would be - considering that it's just straight-up stick aiming, but with 1:1 mouselike aim control stapled on top.
