Camellia is modern and standardized cipher (by means of ISO, NESSIE and CRYPTREC and IETF), uses higher number of rounds than AES, and no attack able to break full Camellia exists (SFAIK).

Camellia cipher suites for TLS are standardized under RFC 6367, including both GCM and CBC modes (with HMAC-SHA-256 and HMAC-SHA-384).

I think they're worth adopting, especially the AEAD modes.
