Choosing among anime model kits & Gunpla is less about a large price gap and more about the kind of build you want on your shelf. The Bandai 30MS Shuremi centers on a character kit with interchangeable display details, while the RG40B is built around a 1/144 RX-78-2 Ver 2.0 in Hatsune Miku Color. Both are plastic kits for the listed 12-16 age level, but their themes are distinctly different.
Quick verdict
Choose Bandai 30MS SIS-Y00 Shuremi if your priority is a figure-kit experience with multiple faces, weapons, hairstyle variations, and optional horns. Choose RG40B 1/144 RX-78-2 Ver 2.0 Hatsune Miku Color if the words Gundam, Gunpla, RX-78-2, and 1/144 define the project you want to build. The price difference is only $0.95, so the character or mecha direction should decide this comparison.

Where each product wins
Bandai 30MS Shuremi
Shuremi has the stronger case for expressive character display. The kit includes three interchangeable tampo-printed faces, body parts, and weapons, giving the build several presentation choices. Its optional horns and two-color hairstyle parts add another layer of visual variation. This is the natural pick when the goal is a 30MS figure rather than a robot-centered build.
RG40B Hatsune Miku Color
The RG40B wins for a shopper specifically seeking a Gundam or Gunpla project. Its title names the RX-78-2 Ver 2.0, the 1/144 scale, and Hatsune Miku Color, while its attributes identify the franchise as Gundam and the assembly status as an unassembled kit. That makes its intended theme immediately clear before you begin building.
Product notes
Bandai 30MS Shuremi (Color B)

Bandai 30MS SIS-Y00 Shuremi is the more character-led choice, with a body, three interchangeable tampo-printed faces, weapons, and parts that let the hairstyle appear in two different colors. The option to display her with or without horns gives the finished figure another concrete variation, making this a good match for shoppers who want a figure kit with several presentation choices. Its limitation is its specific subject: the kit is centered on Shuremi from the 30MS figure-kit series, not the RX-78-2 Ver 2.0 or Hatsune Miku Color concept named by the competing kit. If your target is a Gundam mecha build, that focus points you elsewhere.
RG40B 1/144 RX-78-2 Ver 2.0 Hatsune Miku Color

The RG40B has a very specific identity: its title combines the RX-78-2 Ver 2.0, 1/144 scale, Hatsune Miku Color, and Gunpla wording. Its listed Gundam franchise attribute and multicolor attribute reinforce that direction, giving it a clear fit for a mecha-focused anime model kit collection. The concrete limitation is the assembly format: it is identified as an unassembled kit, so building is part of the purchase rather than an incidental detail. Shoppers seeking the Shuremi kit's interchangeable faces, hairstyle parts, or optional horns should choose the Bandai 30MS design instead.
Final choice by use case
- Choose Bandai 30MS Shuremi for a Shuremi-centered figure build and the character-part variety described above.
- Choose RG40B for the named RX-78-2 Ver 2.0 Hatsune Miku Color subject, Gundam franchise connection, and Gunpla format.
- Use price as the tiebreaker only if both themes appeal equally: RG40B is USD 36.99 versus USD 37.94 for Shuremi, a $0.95 spread.
For most shoppers, the decision is straightforward: Shuremi is the character customization route, while RG40B is the clearly themed Gundam mecha route.
