Yes the pz4 brings a better average dps to the table, but it's all about taking the target into consideration. Or more specifically what the job intended for the tiger is.
Given it's much higher amount of armor and hitpoints (which you really can't argue against) it is perfect for taking on for example SU-85s. Also against targets with a high enough armor the tiger will always deliver better dps than the pz4 (in theory). I would gladly expand the explanation on the matter, but I'm much too tired to do that right now.
TL;DR
While some marginal changes to some heavy vehicles would be welcome I'd argue that both the Tiger and Elefant have their specific roles based on their stats.
