Nope. Pahlavân-î Zrêhbarân are better than Hellenikoi Kataphraktoi except for armour (20 compared to 22). Their morale is decidedly better and their secondary weapon deadlier and more useful against armoured opponents.
Admittedly, the "Noble Cataphracts" are a tad overpriced for their morale, but OTOH their heavier version (Grivpanvar) is the strongest recruitable cavalry unit.
Baktrian Late Bodyguards are slightly better than their Pahlavân counterpart, but fare worse against light units (because of the secondary weapon).
