from what ive heard the EAI cogs are also good but ive never used them
hardly alldasame. There's differences in the the hardness of the steel and precision of the machining, all of which can have a significant impact on the smoothness of engagement with the chain. Also, there are different tooth profiles, such that some brands seem to run smoother than others. I don't like the Surly cogs because my experience has been rough and noisy with them. YMMV.
