(Spoilers Extended) she have the better credientals

So the two candidate for the Prince who Was Promised.

Jon Snow**：** really the only credential he have is that he the son of Rhaegar (Targaryen) and Lyanna (Stark) aka Fire and Ice and that about it. Well and the fact that he the character currently involved in the story of the White Walker (actually the wall)”

Daenerys Targaryen: she a Targaryen and it their prophecy but her biggest credential is that she woke stone dragon when she hatched three dragons from fossilized eggs (and that obviously better)

Like do you want the prince to be the one based on their bloodline or by their deed?
