Except for the features list, how good really are stars and issue counts indicators for anything? Gogs has been around for longer and has received much more publicity, so it's bound to have more stars. Similarly, Gitea has more contributors whereas Gogs is mostly a one man job, so Gitea users might feel more likely to receive an answer than from Gogs. It really feels more like you're comparing the community there than the product.

That said, I agree that Gitea should publish a features list and list the differences between the versions.
