This is not a question with an absolute answer.

As a general rule of thumb, my answer is "15 megapixels".  This is because
very very few people ever make prints large enough for 15 megapixels to be
less than adequate, but people often do shoot at high enough ISOs for any
gain there to be of value.

But that's just a rule of thumb.

Also, the difference between 15 and 18 is small enough, for both issues,
that the other answer is "Doesn't much matter."
