The pedal body is different, and the Ultegras have a metal cap vs plastic. 5th season under a wannabe sprinter kicking over at 120+kg, no straps, and never pulled out. I'd go for money being spent on something that really should be better like seat/bars/stems/shoes/tools etc. The only real draw back is you need a special $5 tool for servicing the 540s. 70g difference in weight too.
No need to get defensive. The bearings on all the pedals are all two bearing systems. You are right.
I'll stand by my evaluation of the clip. The 540s felt very mushy on clip-in and clip-out. Buy good stuff once; I was a unsatisfied with the R540s - the ultegras are worth the money, especially when you can get them for around $100.
