Hey Ettore,

Making that kind of a switch is a huge financial and time commitment. You'll be learning a new program, you'll be learning a new operating system, you'll be learning a new workflow.

But I can 100% guarantee that it'll make your life easier. We've have a number of designers and developers make the switch and Sketch is essential. I made the switch about four years ago—after one day on Sketch, I've never done interface design in Photoshop/Illustrator again. As others have said, it was made for interface design from day one so it is demonstrably better.

To make your life better, these are the three links I send to my designers or my students when they are ready to start learning Sketch. Best of luck!
