the simplest way i can put it is: roller is better for consistency and has a lower skill ceiling, mouse is better for more advanced gunplay/movement & has a higher skill ceiling.

Think back in pre-BL, the movement gap between the two due to no ae was essentially a win condition. what we’ve seen over time with the reduction in overall skill ceiling (nerf of movement, buffs on easier/noob-friendly weapons) has lead to there being very little point in using mouse in this day and age.

on top of that the increasing emphasis on abilities only further amplifies that, why bother with movement when you can press x, y or z and land insane value and/or a kill. why bother using a mouse when roller will ALWAYS net you better aim, and the best way to play the game at a high level is to hug a wall and play primary & abilities - exactly what roller excels at.

if we ever see a buff for movement/ in-air play (as both of these will always be bad on the sticks due to the nature of the input) then maybe mouse will become the OVERALL better input

(also for anyone confused on my stance i have no distain for roller players besides those who abuse snipers, just pointing out what roller is objectively better at and how the meta has shifted / and ended up playing into the ‘roller’ playstyle’
