Roubaix is more comfy than the Tarmac imo Tarmac is more aggressive I found it a bit harsher on the back but if it's what suits you then you will know it. Your money your choice I'd try as many as you can if I were you. I found the SL 3 Tarmac more comfy than the SL4 but over longer distances the Roubaix suits me perfectly I did 100 miles on it last Sunday and the only part of me that hurt was my sunburn. After 50-70 miles on an SL4 Tarmac I felt stiff as a board. Both nice bikes though good luck with your choice.
