If you looked at the showcase, then you already know enough to answer that. However, I think you're laboring under a misapprehension -- that godot needs to be popular.
Unity needs popularity, because that's how they make their money. Free software doesn't have that requirement. You mentioned the supportive community, but the main reason that exists is because godot is a hobby project. People aren't being paid to come here -- they do it because they love godot. Multiply the population of users by ten, and I guarantee you'd see a certain coldness creep into the responses.
Personally, I'm not convinced that unity's popularity is strongly coupled to the number of exciting games made with the engine. I suspect it has more to do with the amount of unity assets for sale. Serious developers seem to put a lot of time into choosing an engine, and most of them will see godot mentioned at some point. Casual developers are less likely to notice it, but they are also less likely to make a great game on their own.
