Not sure what you are saying. In the Android space, only Pixels have a good secure element and Samsung has an acceptable secure element. Of those only Pixel allows unlocking the phone without blowing an eFuse. So, Pixel is currently the only phone that allows installing an alternative OS and provides a secure element.

Most phones without a separate secure element do not protect against brute-force PIN attacks, etc.

As is often said, the most secure phones are:

Pixel with GrapheneOS > iPhone >> Pixel with PixelOS >>>>>> anything else
