Topstone 3 Carbon (vs Grail CF/Diverge Carbon)

Hi,

it is me again. I found all the wonderful and very informative comments very helpful the last days. Next to the Grail CF and Diverge Carbon I have now found this offer. Since I could't decide on the first two bikes yet I would be interested in your opinion since I do not know that much about Cannondale. But the components seem very nice and I really love the color. Sorry for asking again, but it is much money for me, so I wanna know as much AS possible before buying.

Thank you so much for all the help!
