totally agreed.

many people "upgrade" to "better" tyres and say that the braking distance is better, now better cornering, quieter etc.

My opinion is that if your existing tyres are already high performance tyres but an older model and the condition is good, just keep using it.

The 'improvements' you perceive when upgrading to the new model is just psychological.

The only reason why someone would want to get the PS5 is to replace their old tyres or to yes, upgrade only if their current tyres are low end ones.
