im going to be so real im also slacking on gundam watching....... personally for me i wasnt all too invested in 0079 but that is pretty much the start of the franchise so its still worth checking out! i also personally enjoyed SEED, but i havent seen destiny yet. seed isnt perfect (and its a highly. debated series) but for what it is i enjoyed it. ive also heard very good things about 00 and turn-a!
