True, I was just pointing out some improvements that were there, however slight they may be.
Is the new chain that much better? A worthy upgrade for someone who needs a chain and has a lesser groupset?
No, not unless you have $50 - $60 burning a hole in your pocket. It's a little smoother and quieter when clean and lubed, but as soon as it's dirty, it works the same as a dirty 7800 chain.
