Regent Seven Seas, SilverSea, Crystal, Hapag-Lloyd, and Seabourn.
The next tier down includes lines like Viking Ocean, Ritz-Carlton, Seadream Yacht Club, Explora, Azamara, and Oceania.
Next would be mass-market upscale lines like Curnard, Holland America, Princess, Disney, Virgin, and Ponant.
The next tier of mass market lines includes brands like Royal Carribbean and Norwegian.
Expedition cruising is a different market, with different lines and vessels.
I agree with this list, but I would move Princess dow to the same level as RC and NCL. I've cruised both and find them the same (unless you are in the Haven on NCL, in which case I would swap them.)
