Get what feels/looks good to you. It is difficult, at best, to go off of someone else's recommendation. I too looked at the Orbea and the Giant before I went carbon. Got the Giant because of the value and I like the way it looks. Should you get the Giant because I got the Giant? I dunno, but I didn't ride the Orbea because they don't come in my size (well, not the model I was eyeing). The bike shop could get the "right" size Giant and I ended up with that: TCR 2 Composite. I love the bike. I did change the saddle, wheels, pedals before I even got on the bike.
Saddle I changed because of roadbikereview recommendations. Pedals I changed to Look because my other bike has Look pedals, wheels, I changed .. from reading some review. I also worked on the engine too, by the way. I eventually changed the stem to something I liked better (longer) based on my riding style, arm length and flexibility. I now really really love the Giant. My guess is that the Orbea would have felt the same way; So would a Trek or carbon model XYZ, if I had gotten one of those.
Point here is for you to read reviews, then go test the bikes out for yourself and see how you feel about the bike AND these reviews. Then make your decision.
