Graphhopper vs ORS

I’m currently evaluating different routing engines and looking into Graphhopper and Openrouteservice.

According to the Github README, ORS is based on an older fork of Graphhopper 0.13.

It seems to me that both services offer a similar set of APIs, but have grown apart in terms of shared source code.

Graphhopper’s custom model looks quite interesting for my use-case, because I would like to have dynamic and somewhat complex vehicle profiles.

Does ORS offer something like the custom model? How much of Graphhopper is in ORS?
