I'm not saying she wasn't, i'm just saying that neither they nor you can tell whether she actually was. Just that she seemed to be it. Maybe she was the best one, maybe appearances weren't quite that, maybe there were candidates they didn't recognize despite them being better. There are many options. Claiming she actually and factually was the best one is just overconfident though.

And yes, they may have said "she is the best", but that doesn't mean they actually got that right.
