FSA K force SRM or Dura Ace SRM? going on my R3SL, performance differences? Looks as compared to Dura Ace 7900 on the rest of the bike?
Opinions, eh? You came to the right place 
You can’t beat Shimano for front shifting. Go with the DA.
+1.
But I’m blown away by the 111 views and only 1 response!
Shimano DA
.
I have two versions of the FSA (wired and wireless) along with multiple DA cranksets, and I am an FSA man going forward. Better design, looks, and works just as well in any condition, IMO.
FSA looks much nicer, but I’d go with the DA. Loads of issues (i’ve broken 2 FSA cranks - both nicely warrantied I might add). Never hear any shifting issues with a DA crank (although I’ve never had any with an FSA crank either).
