Looking for a road bike

Hey,

so Im looking into a road bike made more for speed and racing. I have went through a lot of brands but on top of my list are these two bikes. But not sure which to choose.
Both bikes have more racing geometry.
But only Rose have Di2, the Canyon has mechanical one. Is this a big deal breaker?
Expect for wheels, both bikes are carbon.

Rose I can get for €2899

Canyon for €2555

Which one would you choose and why?
