One of the confusions is the difference between “faster” and “rolling resistance” and “feels faster”
I think feels faster is largely put to bed. We use to think that harsh skipping feeling was fast, we now know its not
Although I agree that tyre rolling resistance measurements aren’t perfect it seem pretty clear that bigger tyres have less rolling resistance. This is exactly what you would expect once you understand where rolling resistance comes from

There is a Gp4000 comparison as well I think
But of course rolling resistance isn’t the whole story. In a fast group tiny amounts of acceleration differences matter so weight is a factor. But most importantly bigger tyres are less aerodynamic. Whci is why cobbles aside 25mm is the norm for the pros. When you’re as slow as me aero matters less hence the balloon tyres
