Cleartext+signature is better, because, 1. signature can be much smaller than cleartext, so encryption cost is less, 2. cleartext can be inspected, 3. for static content, signature can be precomputed (can't do that with TLS), 4. for static content, cleartext can be sent as-is, for example using sendfile (can't do that with TLS), and possibly more advantages I haven't thought of in 5 minutes.
