nah, I disagree; buying steel (or maybe ti, too) is almost a guarantee that the ride will be compliant. The only thing that could possibly wreck this is some SUPER stiff carbon forks. There would be rare examples, like heavily drawn and/or heavy oversize tubes, or very small frames, but.......
Fit and tyres are obviously important, but steel is forgiving and a little on the flexy side, which is one reason the great majority of racing riders think they can't race on it. I've had about 20 steel and alu frames, and some of the aluminiums have been on the harsh side, but all of the steels have had the charactersitic 'bounce' to them
Having said that, I don't know much about the new Columbus steels, Spirit and Life.
