Daniels seems to be handling things a bit better today. I still don't really think her credibility is the thing that's at issue here anyway, so I'm not sure how much it ultimately matters to the case.
In the most neutral interpretation, she seems like somebody who was misled and taken advantage of by Trump. At first, she just wanted to move past it, but wasn't allowed to because other people were leaking the story. She therefore decided to go public and since then has embellished minor details of her account, and made the most of whatever opportunities she had to derive some financial benefit from it.
But...
Trump still paid her lawyer $130k (this is documented fact).
He still fudged his business accounts (documented fact).
He still likely broke campaign finance laws (to be determined by the jury).
So... even if she is totally making everything up, I don't think it's even particularly relevant. It seems like the Defence are just using this as an opportunity to try and embarrass her or ruin her credibility on behalf of Trump.
