Similar to many people here. I have two steel road bikes, one carbon road bike and an aluminum road bike. The steel bikes are a mix of old small diameter Neuron tubed bike and a modern XCR tubed bike. The aluminum bike is stiff and fast but jarring and anything over a 90 minute ride is no longer in the books. The small diameter Neuron tubed bike is comfortable, feels fast but has a significant amount of flex at the BB. My carbon bike is a modern disc brake bike that is relatively light (7 kg) and stiff. It rides really well but has an almost soft feel in the back and feels unstable on rougher roads. The new XCR bike heavier (8.45 kg) and technically a gravel bike (but with 73/74 geometry). However, it is incredibly smooth, fast and confidence inspiring. I love climbing on that bike. I am not faster than my carbon bike but it feels so much better.
I think one of the benefits of metal bikes is the weight, which gives them a more "stable" feel and the ability to dampen vibrations.
