What is the best cup size? (Patreon)

I really like drawing my girls either in C or D size, its not too small and not too big. IMO anything bigger than E is just way too big and it looks awkward or weird rather than hot and cute. Thats why I rarely draw humongous big boobs. But what size do you prefer? Should I keep drawing small boobies or big boobies? I really want to know which size is ur favorite
