The only difference from the Yokohama Gundam is that
the forearm joint is split into separate parts, as you can see on the right.
Once assembled, it's pretty hard to tell them apart visually. (Basically meaning they're the same thing.)

That said, the 1/144 does have better articulation.

This kit is the 1/144 RX-78F00/E Gundam (EX-001 G.L.R.S.S. Feather UNIT), released to commemorate the 2025 Osaka Expo. The EG RX-78F00/E Gundamand the EG RX-78F00/E Gundam Option Parts Set (EX-001 G.L.R.S.S. Feather UNIT)were released separately alongside it, while the 1/144 title comes as a combined set with both the body and equipment included.

The category naming is a bit confusing — technically the EG is also 1/144 scale. This kit just comes out labeled as "1/144," but it's essentially an HG for all intents and purposes. It seems to carry over the same grade-free classification that was used when the Yokohama Gundam launched, where kits were simply labeled 1/100 and 1/144 without grade designations. Since the 1/100 is a no-grade rather than an MG, they didn't put the HG label on the 1/144 either — so this kit ends up just being called 1/144 as well.

First off, the body is 99% identical to the 1/144 RX-78F00 Gundamthat came out as a Yokohama Gundam Factory exclusive, with the only difference being that the forearm armor is split into two pieces. The design itself is exactly the same, so you can pretty much treat them as the same kit in terms of both design and joint structure. It comes out as a solid HG-quality kit with decent articulation and sturdy joint strength — though the HG polycap quirk where the shoulder pops out occasionally during posing is still there. The previous release was exclusive, but this time it's a general retail release — that's really the only difference.

The G.L.R.S.S. Feather UNIT and armor parts, which are all-new tooling, are a big step up from the EG in many ways. All the solar panels are done with silver foil seals + clear parts instead of plain seals, giving them a beautiful shimmering look, and the backpack sub-arms are now articulated. The large backpack solar panels and the Booster's range of motion have also been expanded, and the beam welding gun is no longer fixed — it's now poseable and swappable so you can configure it in multiple ways. On top of that, the backpack solar panels can be split into 4 separate pieces, and joint parts for displaying them individually are included as well.

Crucially, shoulder swap parts are included so you can perfectly recreate the form as displayed at the Osaka Expo, letting you nail the exact same look and pose. With the EG, the shoulder armor shape was different and the front skirt solar panels restricted hip articulation, making it impossible to pull off properly. With the 1/144, the entire front skirt is swapped out so the hip range of motion is fully preserved, and you can pull off a kneeling pose without any trouble.

And as you can see in the comparison photos above, the Gundam body itself doesn't look all that different from the EG visually, but the joint structure gives the 1/144 noticeably more fluid movement. Add to that the G.L.R.S.S. Feather UNIT that's several steps above the EG version, and the overall value of the kit comes out a solid notch higher. The EG setup isn't bad by any means, but with the HG coming out nearly perfect, it does end up looking a bit lacking by comparison. On top of that, the EG combo runs 1000+1200 yen while the 1/144 is 3600 yen, so the price difference isn't all that huge either.

All in all, as an HG-class 1/144 that addresses every shortcoming of the EG combo, this seems like a kit worth strongly recommending to anyone who wants to build the Osaka Expo Gundam with a more complete look and better gimmicks. :-)
