Nice boobs are nice boobs. Fake or natural. If the A cups are nice boobs, then I'd choose them over the fakies. If the A cups have stupid looking nipples, then I'd take the fakies.
I hate this "natural vs fake" debate. Nice tits are nice tits, no matter whats filling them. You can have nasty looking natural ones and nasty looking fake ones. Alot of fake boobs LOOK natural. And alot don't. Just nice boobs are nice boobs!!!
