Well, you're poll is worded in a funny way, even though I prefer a natural look.
I have some experience on this subject with wives and girlfriends, and even myself and my daughter.
My daughter is an RN who works with botox and fillers. She usually tries to apply/inject just enough to give a subtle effect that still looks natural. 90% of her clients are happy with it. But she's in Los Angeles and occasionally, she gets clients who come back and complain that it's not enough. She's shown me photos of lips that needed and little help, and after she's done they look perfect and natural. But the clients come back and insist that she make them look overfilled, and grossly big and round.
At my wife's insistence (she's 13 years younger than I am), I occasionally get botox because I have a couple of deep furrows on my forehead. It normally looks fine. But once the nurse (not my daughter) used way too much, and I walked around with arched eyebrows for three months. That was ridiculous.
Point is--these procedures can be great when used in moderation to keep a person looking fresh and natural--but taken past that point, they look horrible and sometimes grotesque
A little goes a long way--maybe your poll should reflect some middle ground
