G, easily. I'm a huge fan of everything Imagawa has made, and G has the exact same vibes as his Giant Robo OVA. Also really like 0083 because it's the platonic ideal of UC, but that post military trial scene in the last episode pisses me off as much as it pisses everyone else off. Imo Gundam is kind of bad when not made by Tomino, and I generally don't care for newtype stuff. Just don't find it interesting compared to gruntwank like a lot of the manga and videogames like 0081 or Thoroughbred.
