Not them, but in my experience of trying to get people to switch to Foundry I often barely get past "What if Roll20 was actually intuitive and fun to use" before they're in. I have a whole sales pitch and rarely get through the whole thing xD Full javascript support so the community support is amazing, it's new so it's not anchored in decade old tech, automated sight and fog of war which R20 expects you to subscribe for, It's growing and improving at an impressive rate, it's not even at 1.0 yet. Only reason to stick with R20 as far as I can think is if you've already invested a lot of effort into a system that's hard to support, like 4e, but there's a Foundry system in the works for it so that's limited time.
