There is a difference between tofu flower and tofu brain. Tofu flower is called bean curd brain for short, which is even older than bean curd brain. You can see many small holes when you pull them out with chopsticks. Compared with bean curd, it is tender and has no holes in it.
Tofu pudding is generally eaten with seasonings (oil pepper, soy sauce, monosodium glutamate). Tofu brain should be mixed with seasoning.
As for which tastes better, it depends on different people's tastes.
