Don't forget that Beyer drivers and cups are intercompatible so it won't be too hard to swap the COP drivers for some better ones and keep the customizability (and mic add-on) of the stock cop. That's the route I plan to take as soon as my budget recoups from the cost of a new PC.
Sure. I did just compare the H7 vs the COP, and the only audible difference (connected to a Questyle CMA600i, super awesome amp/DAC so as to hear the full potential of both and A/B fast). Only difference is the H7 is a little less sensitive and needs turned up a few %, the cable is nicer on the H7, and the H7 costs $129 new. Oh, and the H7 can also be digitally connected to PC or PS4.
The COP comes with a mobile cable with an in-line mic, and the plus version comes with a bunch of artistic earcup plates. And costs $199 at this store I'm visiting.
