I was recently looking to upgrade and was looking at R3, defy advanced, Scott, and Roubaix SL3...for me it was Roubaix hands down. R3 was just as much, seemed dated, and i liked the ride of the Roubaix...very stiff and responsive...yet very smooth ride. Three months after the purchase and I love the bike...right decision for me...bike climbs like a goat and takes off when you mash it. With that said, this is based on my preferences...u can't go wrong with any of the above bikes.
