Supergirl has a show with okay ratings on the CW that probably does better in recent years due to people streaming more and the fact that we are still very much in a pandemic.
Wonder Woman's been around longer. She's more of a pop-culture icon and she isn't derivative. There is nothing inherently wrong with being derivative, but Supergirl is derivative with Superman and hasn't ever truly separated from him beyond a storyline. Even the initial seasons of Supergirl very much tied her to Superman.
Just to clarify, someone can initially be a derivative character and find their unique niches like She-Hulk or current Captain Marvel, but Supergirl especially in the show you are referencing is still very similar to Superman that looms over her. Wonder Woman doesn't have that.
Then Wonder Woman is more well known globally. More marketing dollars are spent on her. She does better with merchandising. There are tons of figures you could easily google to support all those points.
