What is the most competitive division in the UFC? There is no way to know for certain but from a quantitative perspective one way to look at it would be which division has the most fighters that are currently active. Based on this metric, welterweight is the most competitive Men’s division in the UFC. We would tend to agree with that and it is no surprise that Kamaru Usman shows up at the top of our pound for pound rankings.
Below is what the graph looks like for the Women’s UFC divisions. Unsurprisingly, strawweight has the most fighters and featherweight… is featherweight.
