Various sources report that the average height of a US male is between 5'9" and 5'10" or a little more. So any bike designed to perfectly fit someone over 6' isn't going to be ideal for the broadest demographic segment.
I'd suggest spending some time in the saddle to see if you can reach a comfortable compromise, and I bet that the other favorable features will on balance convince you it's a great bike.
It's a big decision, do what feels right for you.
