so the material question in kinda moot. and all steel have the same e-module as raw iron so stiffness of the material is kinda moot too. then we have diameters and angles. and then (with only those 2 parameters) its gets too complicated for any human to compute. so i have to go by recommendations. this one ride harsh and this one rides comfy etc etc etc....
you dismiss the good advice with detailed reason, so you have research/knowledge. This then means you also understand what one person likes, another will dislike. If i think a Neo Primato is snappy and quick to accelerate, another person might view it as unstable on descents with a harsh ride.
you chose some 1" quill fork frames. So to speak generally, since you didnt provide specs and its unreasonable to think we would all google each of those frames in detail, the quill stem frames will feel flexible compared to modern aluminum or carbon road bikes. You make like this or hate it- none of us would have a clue.
As already mentioned, find out the frame specs- what are the tubing diameters? What are the tubing butted thicknesses? How long are they? What are the frame angles in your size and do they match they style of riding you want to do?
you claim stiffness of the material is kinda moot due to all steel having the same e modulus as iron. I have no idea if thats accurate or not, but ...i couldn't disagree more with it being moot. Higher levels of tubing are able to be lighter while retaining strength. Larger diameter tubing is also able to be thinner while maintaining stiffness.
Maybe i am misunderstanding you?...
