I’ve looked at these a bit, and while there are definite differences between a gravel bike and a CX bike, I don’t find those differences to be significant enough to justify a gravel bike. I also don’t have many gravel roads local to me (although I have traveled for gravel rides and races). Conversely, there is a 10+ round cyclocross series. That’s where I’ll probably spend my money.
The only thing I like more about gravel bikes is that they seem to be suited more toward comfort on longer rides. I don’t own a road bike, so whichever route I go, that will BE my road bike when the trails are closed, just with different tires.
Options are good, but I’m not sold on gravel bikes as a place to spend thousands…
