On a note of Gundam, an unpopular opinion but I actually do really enjoy how in the moment G Reco is, and while not quite Gundam another of Tomino's works similarly, Overman King Gainer. The latter being vaguely based off of La Compagnie des glaces.

Some people find it harder to follow along in light of a rather anti-expository method of storytelling, personally I find it all the more compelling for story occurring during wartime. Combat is complex, people take action in the moment, not everyone's thoughts or plans need to be spelled out, leaving plenty to inference rather than narration builds for a better story.
