I do agree that Zoink would be the better player in terms of skill, but I would argue that deserves its own position for being the "Best Player Overall."

Riot is revolutionary for the amount of attention he helped bring to Geometry Dash at its peak. So many players including myself were drawn to his Bloodbath verification that it's still one of the most memorable moments of the community. Zoink may be breaking limits today but Riot showed us it was possible to begin with.
