Just over 2k on them so far and still flawless. Bottom line is, the more the bike excites me the more I ride it.
Better? Who cares as long as you like the what they do for you.

The last line sums it up. Other than that they add nothing of value except to the vendor.
I tried a set on my Phil BB and they did not last. They seemed to spin forever when the chain was off, but that's not the way you ride a bike.
You spin the cranks at 60 to 100 rpm and your wheels are turning at about 335 rpm at 30mph. Good quality bronze bushings would be ok for our usage.
