It is not at all obvious which of AES-128 and AES-256 is more secure.
See for example this 2009 paper: https://www.schneier.com/blog/archives/2009/07/another_new_a...
Arguably using a higher bit cipher suite should be considered worse, since it reduces accessibility. 128 bit crypto (specifically the GCM suites) are ridiculously faster, to the point where it is practically free to enable it for all websites. Treating 256bit crypto as better feels like it is missing a key point of security: availability.
