In my opinion, the 6SN7 octal base tube utilized in Cary preamps is the best for a gain stage application. The miniature nine pins used in the Manley shrimp just cannot capture the real magic.
If you are considering the above two, don't forget about the AES preamp, especially the now out-of-production DJH model.
