Sugino 75 vs Gran mighty?
 

Any specific noticable differences?

from businesscycles.com:

"The 'Grand Mighty' crank is a high-zoot version of the Sugino 75 (better cosmetics and held to an even higher technical standard for lateral and concentric runout than the standard model) is also keirin certified and mates with the same bottom brackets as the model 75. Grand Mighty cranks are anodized in a pale champagne color."
