99% of laptop users will notice no difference between 64G of RAM and 16GB of RAM. For example, I am a software engineer with an M1 MacBook Pro with 16GB of RAM for work and a personal M4 MacBook Pro with 24GB of RAM. There is no noticeable performance difference for my workloads.
'Premium' means things like build quality, speaker and microphone quality, camera quality, display quality, etc. etc. These are all things that are much more important to most people than raw specs.
