I work for an IoT company doing vehicle tracking. We wanted to draw a line to show where cars had been. Google's routing algorithm insists on passing every point. GPS errors mean sometimes this resulted in routes going off a motorway, passing an (incorrect) point, and then rejoining the motorway. Graphhopper's map matching algorithm handled this perfectly, and we're a satisfied, paying, corporate user (since March 2019). Tech support was also extremely responsive and helpful when I needed to debug some edge cases (e.g. extremely long trips). My friend Jessie in Germany also uses Graphhopper for visualising research on tram lines, and her experience has also been excellent. I was not paid to say this, I'm just a satisfied customer. Use Graphhopper.
