Dura-ace has a lower stack height,
It also has a central roller bearing as well as the standard ball bearings either end as in the ultegra.
4mm option can be helpful for large feet or highly angled feet as there is greater clearance.
They last forever.
Don't think I need the 4mm option. Does the lower stack height have any advantages?
Thank you.

FatandSlow, funny name :)
While what lyrrad wrote about the extra 4mm spindle length is true, the primary reason is to help riders get their feet in the vertical plane with their hips and knees. It improves power transfer. It's effective when pedal washers and cleat positioning won't quite do the job.
It is extra 4mm better for most riders? What's the scenario when I'd be better with the shorter axel?
I'm 5'9", weigh about 160. I have next to no hips, horrible flexibility, and bird arms and legs. All of my weight is in my chest and back. What do you think?
