Sketch has almost become an industry standard for UI Designers because of it’s ease of use, quick designing, large number of assets and plugins and many more. Photoshop does rule the market too, but Sketch has snapped a large portion of that because of it’s reasonable pricing and host of features. We would recommended knowing the both tools; if ever a situation arises where someone asks you to design in either of the software, you will be prepared for the situation
