I use all of the big three, but Foundry is VASTLY better than the other two. Fantasy Grounds is constantly sidegrading and inventing new bugs while failing to get a proper user excperience. Roll20 works, but is just... there. Nothing interesting happening. Foundry, though, is constantly developing. There are always new rulesets and modules coming out, and creating scenes with it is a blast. Highly recommended.
How are you using Foundry? One of the hosting providers? Or did you set it up yourself? I ask this of anyone using Foundry. I found a docker image that I was thinking of spinning up on AWS, but I was wondering how people were using it.
