Genesis Croix de Fer vs Specialized Diverge 4 Sport Carbon
Both published charts held against each other, on the specs that decide what the bike carries.
The short answer
On everything the frames decide, these two are close enough that the choice comes down to fit and to what you can get hold of.
Assembled from the differences below rather than written over them, so it cannot drift from the table. Every figure is the manufacturer's; nobody here has ridden either bike.
Where they differ
3 of the 6 things we can compare come out differently. The rest are close enough not to decide anything.
Rear rack
only the Croix de Fer publishes a rear rack answerRead from each maker's own mount wording. An adapter is a real cost the price tag does not mention, and 'not published' is not the same as no — it just is not something to buy a rack on.
Fork cargo mounts
only the Croix de Fer publishes somewhere to bolt a cageCage mounts on the fork blades. This moves weight low and off the bars, which is where a heavy bar roll does the most to the steering. A frame with none published may still have them — it means the maker does not say.
Dropper post
only the Croix de Fer publishes dropper routingA dropper cannot be strapped to, so fitting one rules out almost every seat pack and leaves rail-mounted bags at a fraction of the volume. It is a capability and a constraint at once.
Side by side
Including the rows where the two are level, because a spec that doesn't separate them is still a spec you might be checking.

Drawn to scale
Largest published size of each, built from the charts rather than illustrated. The front triangle is the part that decides frame bag fit.
