Genius vs Brain tubing

Looking at 2 used steel frames with almost identical geometry. One is Columbus Genius, the other Brain.
Given that both bikes are otherwise the same, would I notice much ride difference between the mid-range Brain and somewhat "higher" Genius?

Depends on way more than the tubing material.

So the answer is, "Maybe."

From this link:

Genius - Genius tubing was first introduced in 1991. Made from Nivacrom steel, Genius tubing was the first of the Columbus tube sets to introduce "mega oversized" tubes. Genius tubing saves weight by only butting portions of the tube that are under the greatest stress. Using Genius tubing, we select from 3 different sets to accommodate small, medium and large riders. Genius tubing can be constructed using lugged or luggless techniques. Columbus offers special Genius lugs to match this tube set. Genius tubing makes for an excellent road or track bike. Please click on the tube decal to see our standard set.

Brain - We strongly recommend Columbus Brain for cyclecross designs. This tube set is an excellent choice for creating a light, tough and strong cyclecross frame. Brain tubes feature round over-sized diameters that offer good resistance to accidental impacts. This allows for excellent durability for the life of the frame. Brain Tubes can either be lugged or fillet brazed. Large choice of wall thickness and butted diameters to strengthen your cyclecross frame. Brain tubing can also be used on either a road or track frame.

Brain only comes in standard "oversized" dimensions whereas Genius has more options in terms of tube shapes and sizes (although about 90% of the Genius frames out in market use the same external tube dimensions as Brain). Genius tubing is killer thin thus it will build into a light, but somewhat flexible frame. Brain is significantly thicker and more suitable for rough use, or if you want a stiffer frame than Genius will afford. Both good tubesest, but different.
Becareful buying/selling bike parts on-line. I learned the hard way. :(
