I was trying to match my new gravel bike to my perfect-fit road bike a few months ago. Initially, the reach on the gravel bike was 1-2cm longer (to the hoods) and because I hated that handlebar anyway I got a new one with shorter reach/drop and it got them much closer. Gravel bike has a bit more stack (7mm I believe), and overall the geometry makes the gravel bike feel less stretched out. While this slightly bothered me when I was riding it a lot on roads in the winter, and was about to fiddle more to match them, now that I've been riding the gravel bike on some flowy double track trails it is 100% perfect. If I only used the gravel bike on long gravel roads that were the same as my paved road riding, other than surface, I would try and match. But for the gravel riding I do this bike is just fine.
