It depends on what you’re doing
Just a quick observation from my experience. We have a hill that is a descenders dream. I reached 63 MPH on my 88 Cannondale and it was rock solid. The only thing that slowed me down was that I ran out of gears. Then I descended it the next day with the same weather conditions on my trusty steel Bianchi. At 55MPH it started getting a little squirrelly and at 58 I nearly wet myself. Despite this the Bianchi remains my favorite bike for long rides due to its softer ride. So, in this case, stiffness does matter.
