I don't like either, so I will tell you what it needs.;
-Miniguns on each arm
-Rocket pads on the shoulders
- Jet boosters on the legs for the emergency maneuvers
-Cannons the the upper outer parts of the arms.
-blades that rotate with the mini-guns, that wayyou got a wicked weapon when out of ammo.
-Lasers and infrared beams on the helmet, to fry electronics of enemy vehicles/weapons.
THat is all I can come up with frm t of my head... but that is how to make it just plain beasty!
