Best modern shows are IBO and Thunderbolt. Thunderbolt is an off-shoot of the OG series (1979). OG shows, you can't go wrong with watching the 1st MSG and Zeta. ZZ is underrated because of the tone shift.
Wing was garbage on my rewatch, couldn't make it through.
G Gundam holds a special place in my heart. Think DBZ w/ mechs.
Gundam SEED is pretty much just a remix of the OG show, but with worse writing. The mech designs are A1. Stay away from Destiny.
Reconquista is confusing af.
00 is very good. Preachy at times, but I enjoyed that show in its entirety.
Unicorn is a continuation of the OG, Zeta, ZZ, Char's Counterattack (movie). Garbage imo w/ an even whinier MC than Zeta. Mecha designs saved this show because there wasn't too much memorable about it imo.
Turn A is confusing as fukk, but it's good.
08th MS Team has a general consensus of being the best overall show. I didn't fukk with it too heavily, ask the breh
@42 Monks if you're interested in it.
Build Fighters is great, Try is trash, Build Divers is garbage, Build Divers Re-Rise is great.
IBO put Gundam back on the map and is a great entry into this series. Easily Top 5 in Gundam media for me.
0080 War in the Pocket is piff. 0083 Stardust Memory is heat as well. Char's Counterattack is heat. The early movies are all really good.
