well the jagdpanther could defeat any other tanks in ww2, even other german tanks
That could be said of many armored vehicles which came late in the war. Depending on range and aspect, just about anything could kill anything else. Granted the jagdpanther had great armor and a superb gun, but don't think for a second that the jagdpanther would go unscathed against the M36, the Su-100, or, God forbid, the Su-122.
The real question would be how much of a detriment the limited gun azimuth would be in AH? Since most GV fights seem to be static slug-fests (and I'm certainly no GV'er), I'm guessing the jagdpanther would kick bellybutton quite nicely.
