If you want to see the claw used effectively in modern wrestling, look at the way Akiyama put it over in his 2020 D-Ou match against Higuchi in DDT.
I only got into wrestling in 2015 so I'm a fairly new fan and I have no issues with the claw when it looks tight on the face. I also popped huge for O-Khan stopping an Ibushi knee with his claw but that was because it was glorious silly anime bollocks.
Also this is an obscure reference but I've been completely sold on the claw since I saw Yuen Wah destroy Yuen Baio with it in the classic 80s Sammo flick Eastern Condors.
(can't believe my first post is about the claw lol)
