As with this list's previous incarnations (2018, 2019), every wrestler was judged based on the full breadth of their performance skills. These include, but aren't limited to, in-ring capabilities, technique, athleticism, character work, storytelling, grasp of psychology, presence, aesthetics, and charisma. The ability to connect with crowds is a big one. In any artform, the truest measure of a performer is how they engage their audience, thus excluding performers who aren't consistently over.
It should also be pointed out that a number of these categories are mostly subjective. Your own Best in the World list may vary, so please throw it down in the comments section.
As usual, this kind of article creates many honourable mentions. Brock Lesnar and Johnny Gargano have been too inactive for inclusion right now, as the title dictates. Kenny Omega, Becky Lynch, Matt Riddle, and WALTER aren't putting forth peak performances at the moment. Seth Rollins, KENTA, and Rhea Ripley are surging, but narrowly miss the cut, while David Starr and Jordan Devlin miss out by the narrowest of margins as well.
A caffeine-dependent life-form from the frozen wastes of north east Scotland. He once tried to start a revolution but didn't print enough pamphlets, so hardly anyone turned up. Give him a follow @andyhmurray. You'll have a great time. Maybe.
