Wilchq is a rubberdome keyboard user, yet he developed his skills to almost perfection and can keep up to other pro players who are using mechanical.
From my own experience - i moved from old shitty rubberdome into mechanical with Cherry MX Red. It had, to not lie, huge impact on my gameplay.
From main points - it made me faster, even considering my weak and small hands, i wasnt able to keep up on 180 bpm with rubberdome, mechanical made me instantly consistently play 200 bpm, going into 210 single tap was matter of getting used. Another thing - i tap way lighter which preserve a lot of stamina. On rubberdome maps like Crimson Belvedere (10min Demetori marathon) was impossible to finish, i don't have this problem with mechanical at all. And many minor like - more stable UR, more stable acc and which was annoying at start - a lot of sliderbreaks becouse actuation point of mechanical keyboard is way diffrent and way more sensitive.
Basicaly - mechanical keyboard matter for people who strugle becouse of physical issues but i think you can be as good with rubberdome if you train enough (which Wilchq case proves).
