My interest is audax, so long distance riding, with limited recovery time. I have a tarmac carbon bike and moved from 23mm to 25mm tyres, which was the best I could do. On a multi-day ride in 2017 I got nerve damage to my fingers and toes which took 4-5 months to resolve.
I've now bought a Genesis Equilibrium disc with 28mm tyres. They are very different. The Genesis feels as though it has less vibration, not just because of the wider tyres. It is well-planted, less twitchy, possibly because of less aggressive geometry. It feels good on the flat, with a flat portion on the bars, which helps hand position and comfort. It descends well and feels very stable. I've fitted guards as a permanent fixture.
The tarmac definitely climbs better though, and feels more exciting to ride.
It helps to remember that major purchases are always a compromise. For cars for instance you need to weigh up performance, room, cost, number of seats etc. You weigh them all up and get the best fit. Bikes are no different. Most of us wont get everything we want, and need to choose our compromises to suit our pocket and intended usage.
So you pay your money and make your choice as the saying goes.
