Jagdpanther is considered the top tank destroyer of the entire war. As Yustax says, it was very, VERY fast, great protection, WONDERFUL gun and optics, low profile, and above all, the lack of a turret does not make it a poor tank, considering the Jagdpanther was purely used as an ambush tank. It didn't NEED to have a big clunky turret to destroy its low profile and create weak spots.
