I definitely don't agree that the Exploiter Wizards get greater exploits. It's not intrinsic to the Arcane Exploits or Exploiter Exploits that at level 11 you can pick greater exploits. What grants that is the explicit ability "Greater Exploits", which allows you to sub a greater ability when you pick an exploit.
The Exploiter Wizard does not gain this class ability and thus cannot pick greater exploits. I consider this an important distinction keeping the Exploiter Wizard in check and not simply being an Arcanist+.
