I'd sum up my personal recommendations:
* Avoid RSA keys below 2048 bits, create new keys with 4096 bits but
  2048 bit keys can stay if you already have them
* Avoid DSA keys
* Avoid ECDSA keys
* If you like to have fancy new elliptic curve stuff use an ed25519 key
  instead of ecdsa. But RSA-only is okay, because you'll likely need
  that anyway for compatibility reasons
* Completely avoid SSH v1 keys
