Would you rather get a power armour (Like space marines, Iron man or Spartans etc.) or cybernetic (Robocop, Halo spartans, Deus ex etc.) upgrades?
Note that the power up wether suit or body would be roughly equivalent in their effects. The main difference being that the cybernetics are always with you and cause major changes to your body while the suit leaves your body the way it is now but can be lost and you might get in danger while out of the suit.
