Those coins have a very different goals and target group, it's hard to compare them, so such questions like that one in the subject are even harder to answer. Personally, despite my antipathy for Libra (I have very similar thoughts like statements in this article: https://www.blockchain24.co/libra-not-such-a-promised-land/ ) I think it won't change much on the market - it will be strongly bounded with Facebook, so I don't think it will influence Bitcoin at all
