I picked up a Diverge this past weekend, the Pro Campagnolo LTD version in size 56. I tried a size 54 of the previous gen for comparison and felt a bit cramped in the drops. My road bike is a Ridley Fenix size M with a 130 mm -20 degree slammed stem for comparison.
Originally, I was planning to wait a bit longer before buying and test ride a couple other bikes. I was also considering some custom options, like the Seven Evergreen. But the Diverge felt so good and I was worried enough about it being sold (the stock of Diverges seems pretty limited nowadays and they seem really popular) that I ended up going back and buying it after agonizing about it at home for an hour 
I’d been riding a converted steel road bike as my gravel bike so it’s kind of an unfair comparison, but the Diverge feels incredible on both asphalt and gravel. It’s super stable but still feels really agile - so, so fun to ride. It seemed to me like the faster I went, the more comfortable the ride got.
It was a lot faster on asphalt than I was expecting it to be, like @DaveWh mentioned it’s probably due in large part to the stock tires having the slick tread down the center. I’ve heard that this can cause some wheel slip issues in wet conditions (something I’m not too likely to encounter in San Diego).
