1: Most main steam anime (The mega-hits that go for 300+ episodes? Yeah, those ones) is simply out done by it's own manga. Stories like Naruto are completely ruined by generally badly handled anime. I genuinely like most of the manga, but the anime is almost unwatchable. Bleach is pretty much the same.
2: FMA: Brotherhood is perfectly watchable, and I certainly prefer it over the original because it doesn't leave gaping plot holes and most of the plot lines built out of convenience are done away with. Then again I also skipped straight to the new content.
3: Everything else? Generally I'd recommend Japanese dubs w/ English subs whenever you can help it. Often times they're just better. It's not always the case, but not everything gets to be Cowboy Beebop. Often times though there's just things in Japanese conversation that just do not translate well into English.
And some recommendations...
Baccano
Gurren Lagan
Ruroni Kenshin
Trigun
Foolie Coolie
Black Lagoon
Ghost in the Shell (SAC)
Anyone with Miyazaki's name attached to it, or Studio Ghibli.
And some more.... questionable ones. Watch them at your own risk and expect brain fucks as a result of having watched them. Generally I'd avoid trying to digest too many episodes at once. I watched Evangellion in one sitting and that damn show fucked me up for at least two weeks.
Neon Genesis Evangellion.
Serial Experiments LAIN.
Ghost in the Shell (movies)
Welcome to the NHK
Ergo Proxy
Of course on the other hand these shows might just fly over your head. Ergo Proxy I had to read explanations to pick up on everything, and I literally fell asleep watching the second Ghost in the Shell movie. After forcing myself to stay awake when I watched it again I just got a migrane from it.

It's terrible. Gaping plot holes and shameless fan service crammed right into the middle of what's supposed to be serious plot construction, a plot line that utterly deviates from the source material because the director felt "just cuz." It's a mess of an anime and the only people who legitimately think its good are being distracted by the gratuitous gore.
