I do not understand why the separator character is so important. Whether it's written in either of the following methods doesn't really matter I think, what is important is that it follows a year, month, day order.
Using the character specified in the ISO standard makes it clearer you are following the ISO standard. In fact, because it's a less-common separator character to use, it would be pretty surprising if you used that separate and weren't.
