I recommend the Fullmetal Alchemists. Both are great.
Lately I've been marathoning the Gundam Franchise. If you stick with shows set in the Universal Century timeline, you're in for a treat.
UC Gundams:
The Original (either movie trilogy or tv series. Take your pick, I personally prefer the tv series, but most people recommend the movie trilogy), Z(eta) Gundam, ZZ (Double Zeta) Gundam, 0080, 0083, 08th MS Team (Not as good as I remembered, but most people seem fond of it), Char's Counterattack, F91, Victory, and Unicorn.
