If it's your goal to have a character dinner, I would say 1900PF is pretty good for dinner. Granted, no WDW character buffet dinners will have stellar food, but I thought the options were a step above the standards for most character dinners. I also personally think that the quality of character interaction was better at 1900PF.
IMO, if you're trying to go to 1900PF, I would go for breakfast. The characters are different (winnie the pooh, tigger, alice, mary poppins, and the mad hatter are the standard breakfast crew), and I liked the food a lot more.
