I’m 8 episodes away from finishing MSG79, it’s taken me far too long (probably a few years of intermittent watching).

What would you recommend I check out next?

I know 08th MS team is highly recommended. I loved Witch from Mercury, admittedly I watched most of it on my honeymoon traveling Japan, so I might be biased. Also open to non-Gundam Mecha suggestions, I started The 86 and enjoyed the premise.
