I wouldn't go back to Roll20 if they paid me. FG has a better class of player and GM IMHO.

Every time I see someone advocating Roll20 on social media I always suggest FG. They always respond with 'but Roll20 is Free' I don't think they have done the math or considered paying for FG monthly. Its another misconception. Paying monthly for Ultimate is not that well known in the wider world. Everyone thinks you have to pay $149 upfront. When I tell them that you can pay $9.99 a month for FG (The same as a pro Roll20 subscription) they are always surprised.
