Okay, if you're looking for something better than 8th MS team, that's pretty damn impossible.
But, if you're looking for something as-good-as, I'd reccommend 0080 War in the pocket (realizations of war in a place few ever thought it would come) and 0083 Stardust Memories (sets up the events leading to Zeta Gundam and has some damn good mecha).
Also, a must is of course Mobile Suit Zeta Gundam, most arguable the best damn series in the UC century (mostly for drama and plot though, not realism)
So any of those would be a good bet. Also, stay away from SEED/SEED Destiny. I cannot stress this enough. Also Wing was good, but doesn't stand up to the UC-era Gundams.
As for G-Gundam... that's in a category all to itself.
