I do some graphics work and I wouldnt say that there is a world of difference between the capabilities of Illustrator and Figma. Photoshop is obviously a completely different tool. Very textural digital painting of the kind that photoshop excells at would be pretty tricky in a browser. (Theres a webversion of Heavypaint now, but thats vector-based of course.
Check out Photopea, it has a ton of features and is fairly performant in the browser. It also seemingly copies the UI of Photoshop but impressive nonetheless.
