Actually there was no prototype competition. The first eleven Jagdtigers had the Porsche suspension, the rest up to around 70 had the Henschel suspension. In spite its obvious advantages, the Porsche suspension had some flaws that made further refining necessary (vibrations that in time threw the gun out of calibration), and so it was decided that the Henschel suspension should be used in order not to disrupt production.
The subject is covered in detail in the Spielberger-Doyle-Jenz book "Heavy Jagdpanzer", published by Schiffer
