I would recommend Full Metal Alchemist Brotherhood. I thought that was better than the original. If I remember correctly, the first 10 or so episodes are a condense retelling of the first 18-20 episodes of the original series but after that, it's a completely different story-line.

As for Yu-Gi-Oh!, I never watched beyond the original series, which aired on KidsWB on Saturday mornings, so I can't comment on any of the other shows in the series.
