Best spot up 3 point shooter, sure. Even as a very high volume spot up shooter.
But as Ingles has repeatedly acknowledged himself, the quality of the shots he takes is significantly easier than those taken by the true elites, the Harden's, Curry’s, even on some level Mitchell, who take every shot off balance, falling away, off the dribble, with a hand in the face.
Ingles is still a star though. Every team in the league would happily add him to the roster as he makes the guys around him better and is essentially a point forward 3 and D guy, which is very rare.
