Out of interest I thought I would compare pull-ups with my recent chin-ups. Pull-ups are widely accepted as being harder, and some people claim "better".

With 2 minutes rest between sets to failure I managed 3 - 2 - 2 - 1.

Around about the start of Covid I managed 5 pull-ups, and after short rest, 9 chin-ups - these remain my life-time records. Those were the days!
