I also prefere girl with smaller boobs though sometimes the flatness is overly to much... even with clothes on you still sould see a considerable curve but often its barely shown( as exemple take Blanc/ White Heart her flatness is to much for someone being hundreds of years old lol.

What i dont likeat all is those oversized boobs which many characters have and get... which doesnt make a character cute anymore and sometimes even give an appealing look to them.

But this doesnt mean i dislike boobs.

If they are in a correct and agreable size

Flat definitely

Oppai will always be the one for me! Here's best goddess!

I believe both to be amazing in their own unique way

Quite the big difference there. As it should be.

With oppai the sky's the limit however with flatness you don't have to worry about your waifu having back pains

Every person needs a little bit of both from time to time
