Which tool to use: Sketch, Photoshop or Figma? (10 minutes)
Figma is the latest one and the most easist to use. It works on both PC and Mac. But it's very far from industry standard and hard it would land you job at web design studio.
Sketch is industry standard now, it's easier to use than Photoshop, but it's Mac only. If you are on PC, you would need to fight with Hackintosh.
Adobe Photoshop is still industry standard. It's harder to learn, compared to other from this list. It works on both PC and Mac.
Adobe XD is Adobe's response to Sketch. It's far from industry standard.
Adobe Illustrator is rarely used for web design and it never was and it never would be industry standard. So forget about it.
