People who don't draw but have a graphics tablet. What's your experience?

I'm a professional graphic designer, working with my mouse and keyboard for over 10 years (Photoshop mostly). And I've seen many colleagues opting for a graphic tablet instead of using a mouse.

I was curious to buy one to test, but today I can do everything with a mouse because my niche doesn't need me to draw. And I would like to know the opinion of colleagues here on the sub who don't draw, but use a graphic tablet, what is their experience, do they think it is something necessary?
