i'd say neither, as they both can be fine or done wretchedly.
how so? well, a classy romantic work is sexuality at it's best,
while some sort of horrid hentai-esque smut is it's worst.
at the same time, realistic violence designed to show the
depravities of war -such as the message behind some MOH games-
and thus decry it via a method similar to what M*A*S*H did back
in the day, is a quite poetic way of showing violence in a work,
but some sort of messed up mindless slasher movie is just B.S.
i suppose that is all i have to say about this right now.

Wait... didn't you already make this poll once before? I'm quite sure you did.

I'm not a squeamish person. However, violence will always have the extreme edge over nudity.

Neither. Morally they're both inappropriate and I see them of the same level. Unfortunately because of how our society works explicit sexual acts are becoming more acceptable. If you ask me; if they can allow some fondling to be shown in prime time, they can show some head-bashing too.

Overemphasis of one and not the other. If you can show a head blowing off, you should be capable of showing certain other things being blown as well.

Depends on where you live and the demographic.

Euro-customs assume children don't know people can even bleed. However, they allow for a bit too much implicit content for kids.
The Americas (North and South, for the most part) assume kids don't know that mommies and daddies sleep together to make babies. However, they allow a bit much in the way of violence to those between 11 and 15.
Asia is fucking crazy and has batshit insane standards and legal practices.
Africa doesn't have time for entertainment, the kids are having sex and being enslaved and being trained to kill daily.
Australia is Australia.

both are fine but they do have their limits at a point

This question is all about situation. Such as...What's going on...why is it violent or sexual. Sometimes the intent behind a situation is worse than the situation itself, you see. You also have to take into acount that both of them are bad, but for different reasons. One is because it injures a fellow man and the other with insinuates sexual scenes and instances are only for joy or pleasure. I'm sure it's not the answer you were looking for but I just wanted to speak my mind.
