Best-sounding (or least annoying) Grunt on ATP Tour?


Hall of Fame
Clearly, the least annoying grunters on the ATP tour are the players who don't grunt at all, BUT among players who do grunt, which would you say has the best-sounding (or the least annoying, if you can't choose a "best") grunt?

I nominate Dominic Thiem. It's pretty audible, but it's not shrill or contrived, nor is it annoyingly protracted. I feel like it also matches his shots quite well.

This is like asking what the least bad truck nutz are.

Grunting is totally unnecessary and trashy as ****.
This is really not true. Hitting hard requires an expulsion of air, which sometimes translates into a grunt. My anatomy professor actually made us do a bit of research on this in college. Part of the reason why I quit and did a math major instead.

However, I will say that a vast majority of players may do it out of habit rather than because of the effort they are putting in.
