Carillo, new R&R, or Cunningham rods for 5.9

Is there a preference among these rods? Ive been reading through countless threads for days. I realize there is no correct answer, but any reason to buy one over the other maybe?

I went threw the same thing this spring when I ordered rods. I went with the Wagler rods because they fit my budget and design I thought was better than the cheaper Carrillo. The best rods in my opinion would have to be D&J precision machine due to overall design and pressure lubed wrist pin. The Wagler rods utilize 12v style bearings, have a lube hole in the pin end, rod cap has machine fit locking grooves with ARP 1/2" L19 bolts, and rod caps come oil clearanced. I don't know much about the new R&R or Cunningham rods so Hopefully someone has more info for them since I based my decision off Wagler vs Carrillo.

I found a set of R&R I beam for a steal so if I'm going that route if they still have them
