Still wondering this myself honestly. I'm still on v0.14 on my setup and I'm guessing when I finally upgrade it's going to force me to make a choice. I probably can live within the limits of EE free tier if I stay relying on relays but I could see if I moved to a more mesh approach later, 50 nodes isn't all that hard to hit. I don't need multi users/user management or any more ACLs then what I already have, so I'm leaning towards staying in the community edition unless I see a reason to go EE. I wish there were more in depth docs on the full feature differences between CE, EE Free, EE Paid.
