I have used roll20 now for the past two years and love it. I have also tried every other digital tabletop software. The others are inferior to roll20 except in one important area: THE VISUAL STYLE OF THE INTERFACE. Honestly, roll20 just doesnt look very good. It's just kind of basic and ugly. In my opinion, roll20 should take a few cues from Fantasy Grounds and improve the overall aesthetic and design of it's otherwise superior product.
