So steel can be comfortable or harsh even at the lower end of the market. I am sure the same is true at the high end too. How a frame feel to ride will have alot to do with bulk modulus of the frame. The modulus will be different in different directions and is not just dependent on the materials properties of the steel itself. It is more dependent on the wall thickness of the tubing, size of tubing, geometry of the frame...
So quoting yield strength or Young's modulus figures for the various steels used as that what I see on columbus/renyolds website is kind of meaningless as it tell you little about the bulk modulus of the frame in a given direction which is what governs how stiff it. However the frames stiffness will be only part of how it deals with vibration from the road. The other is the energy lost as the frame distorts. The more energy turned into heat really the better vibration damping qualities it will have. This is hysterisis. I am sure the guy's/gals at enigma will be able to build a frame to your riding preferences.
I'm a Guru guy through and through. I have a Geneo now and an Evolo on the way, so if I were thinking steel, I'd lean towards a Sidero. That having been said, Spirit isn't the stiffest tubeset ever made. I had a Cinelli spirit a few years back and as much as I loved it, I always wished it had been a tad stiffer. If I was looking for a steel race bike, I'd probably call Waterford. The S3 tubeset they use is supposed to be the stiffest steel tubeset made. Obviously geometry and such helps as well, but for arguments sake. We'll say if all geometry were identical, the S3 should (and I know someone will say otherwise)be stiffer.
It also depends on your location as well to an extent. If you're in North America, Waterford makes sense. If you're in Australia, Baum would be a good choice and if you're in Europe, a well kept secret to us North Americans is Duell. Or even a Zullo.
Discussions on Titanium will be all over the place. No other metal is so dependant on the builder for it's ride characteristics. I've ridden well made ti frames that were too noodly to be raceable and some that were perfect. I think that unlike any other material. Every ti frame has it's own soul.
Granted, if i was a pro, neo pro, cat 1 or 2 rider I'd be on carbon. But I ain't. I'm a lumpus, and I ride on shitty roads. If it was road heavy, was a noodle or couldn't climb, then of course steel would be in the dungeon of history.
Another fun fact: Dutch magazine Fiets tested the shock absorption of bike frames by electronic measuring shocks and their tentative conclusions were:
1. Saddle and tires are much more important
2. Heavier bikes tend to be better in absorbing road buzz => Which correlates with the "Steel is more comfortable" line. That also is in line with above poster who says his cheapo Crmoly frame is very comfortable
Besides, Alu wins the vulnerability/weight/price game

Considering I'm a steel afficinado and was in a conundrum between Spirit and EOM 16.5 it was a fun read.
Enigma is a good builder, so it wil be fine as long as the contactpoints will be in the right spot.
