It doesn't really matter-Orbea so far has not built any decent carbon frames.
Neither light nor stiff...as mentioned they don't get the best out of carbon but they have the best rider which covers the weaknesses
Orbea has not built any decent carbon, nor aluminium frames...

I have an alu Orbea and it's heavy and wobbly. :madman:

that's why I need something better.

There a lot more to a bike then weight and stiffness.
The question is what is the best Carbon Frame, weight and stiffness are definitely factors but not the deciding factors. Long term durability, ride quality and geometry are arguable the much more important. Weight and stiffness are just easiest to measure, the others can be rather subjective.
My wife raced my 08 Alma for a season and then for the past two years I have ridden and raced it just about exclusively. The bike has close to 10,000km of hard off-road miles on it with zero problems from the frame. It may not be the stiffest or the lightest bike out there but in the important durability category it has to be the near the top.
Of course my major complaint about it is the single water bottle mount on the small frames. Fortunately for us vertical challenged people that has been fixed on the new frames. (Oh and the new frames are built around a 100mm fork).
Long term durability is not an important quality for race bikes, you can have a new frame every race, but important for someone that wants to keep the bike for some years. Difficult to measure but I may also say If the frame is stiff it's strong, if it's strong it's durable!
Ride quality, I suppose you mean comfort, it can be and it's measured, no problems here to me. If I need more comfort I may add a more forgiving seatpost.
Frame geometry is also important but any decent top level race frame as the correct geometry for it's purpose. And if it's the best it's a top level frame.
