I never had an issue with gyro controls when they first started appearing, but I never really got to use them much until I got a Vita and tried games like Uncharted:GA and Killzone, then I started to see the benefit it can add. It wasn't until I got a Switch and Splatoon 2, that I truly realized how amazing it can be when done right. I mean, it is truly a game changer with how much faster and more accurate it lets you be play compared to sticks. There's also the fact that I don't have to deal with finger cramps maneuvering the sticks for long periods, it's much more comfortable.
When I first joined Splatoon 2 online mode (gyro disabled), I played against people of similar player rank to me and my scores were not great; after I switched to gyro aiming, the matchmaker started putting me against people significantly higher rank than me. Surprisingly, I top the match scoreboards almost every round, still up against high rank players, and I don't think that's because I'm a more skilled player, the controls really do help.
For those of you still burned by the Wii, try something newer with a good motion control implementation (Splatoon 2).
You don't have to waggle or flair your arms, or even put much effort into it, just move your wrist.
