If we compare data from the entire careers of Alcaraz, Sinner, and Zwerev and look at the winning percentages of rallies lasting up to 4 shots, Zwerev actually has the highest career percentage among the three. The margin is small—he holds 42%, Sinner 40%, and Alcaraz 41%—but he leads this category.
Looking only at first-serve points, given Zwerev’s outstanding serve, he also shares first place with Sinner, who is serving nearly as well and finishing points in just a few strokes.
