Just passing by to tell ya i'm likely gonna read those two by January, though I'm more likely gonna watch the movie trilogy for Gundam instead of reading the manga since it's both likely faster and I can't find it in mangaseeonline.us.
Sending a link for where you read those would help a lot
It's watch for both. Legend of the Galactic Heroes is an OVA series based on a novel series and if you're wanting to read the novels, it'll cost you unless you have Kindle. There is a manga for it, but it's a poor adaption, particularly due to its art style and pacing.

There isn't that many chapters translated though, so I'd say watching the movie trilogy first and maybe spending money on the actual volumes is better if you become invested in the franchise. The plot is the same in both, though The Origin is a remake that adds a layer of depth to the series due to the world building having become far more fleshed out by the time of its release. It also offers a good level of characterisation to its cast, especially those that were just supporting characters in the original series, though you can watch The Origin OVA series which adapts the flashback segment of volumes 5-7 as a prequel to the original series to offer a more complete experience for the series' animated form.
