Sporti silicone caps vs Speedo silicone caps? Youth caps?

Does anyone have an opinion on which is better, Sporti silicone caps or Speedo silicone caps? The Sporti ones are cheaper, but do they last as long? I've been using the Speedo caps. They seem to last forever, but they do get stretched out and then start to creep up my head when I'm swimming (especially coming off the wall), which is really annoying. I'm also contemplating getting a youth cap instead of an adult cap, and wondering if other women with small-ish heads have tried this. Together we can fight cap creep! Oh, and happy Thanksgiving! :turkey:
