Wii waggle doesn't compare to VR motion controls. I owned one and I was seriously disappointed that everything was too abstracted, you literally flailed your arms randomly and shit happened on screen, VR though is 1:1 controls, it's having your hands in game. Don't dismiss it without trying it for yourself, you might find it more fun than you think.
And nothing is more precise than aiming the gun yourself. I played FPS games on PC and consoles for decades, but once I played in VR I instantly became faster, deadlier and accurate, and I don't mean slow VR-only shooters like Pavlov and shit, I mean Quest ports like Quake 3 Arena or Doom. Rocket jumping has never been easier.
I definitely agree VR has way more to offer than Wii waggle ever did, but Wii still had a few cases where you could use the remote as a light gun like with RE4:Wii Edition, and that felt amazing. I was shooting knives out of the air by instinct alone, and aiming for the zombies by pointing the wiimote at the zombies really felt like something better to me. VR is a whole other level beyond that though.
And yes, shooting in VR is even more enjoyable and accurate than M+K. I'm not sure it's necessarily faster as M+KB is tied to a small wrist motion where VR is life-like you hold a gun and point and shoot so you need to move your entire arm, but that in turn makes it more precise.
