We've done both & I vote for 1900 PF. Food at both was okay---nothing stands out as horrible or wonderful, just regular buffet food. Character interaction at 1900 PF was great! DD was dressed as Cinderella, we were seated in the main dining area near the buffet, & she was able to dance with both Prince Charming & Cinderella. If you are seated in another section, you won't be in the middle of the dancing, but the character interaction would still be good. CP character interaction was fine, just took longer since the restsaurant is divided into two sections with the buffet in the middle.
