Digital design requires a different sensibility than print. There is a heightened emphasis on visual impact and courting the viewer's curiosity. I would argue this is true not only in digital and social media ads, but also in web design.
Picking one type of design as the one you like best is a little bit like picking which child you prefer. Nevertheless, if you and I are chatting candidly, it's installation design that makes my heart sing at the highest frequency.
