[SD] SD EX / SD CS / Sangoku Soketsuden / SDW / Gundam Converge

Bandai offers several SD (Super Deformed) lines of model kits, each with its own unique style and features. Here are some of the main differences between them:

1. SD Gundam BB Senshi: This is the original SD line from Bandai, which features chibi-style versions of Gundam mechs. These kits have a simple design with limited articulation and detailing, making them easy to build and perfect for beginners.

2. SD Gundam EX-Standard: This line features more detailed and articulated SD Gundam models than the BB Senshi line. The kits come with a wider range of accessories and options for customization.

3. SD Gundam Cross Silhouette: This line features SD Gundam models with a unique inner frame that can be extended or shortened to match the proportions of the character in its "short" or "tall" mode. The kits offer a high level of poseability and detail, making them great for intermediate builders.

4. SD Gundam Sangoku Soketsuden: This line features chibi-style models of Gundam characters reimagined in a Three Kingdoms-inspired setting. The kits have a unique aesthetic with ornate armor and weapons, and the characters are highly detailed and articulated.

5. SD Gundam World Heroes: This line features chibi-style models of Gundam characters from across the franchise's history, including heroes and villains. The kits have a simple design with limited articulation and detail, but they come with a range of accessories and interchangeable parts for customization.

Overall, the main differences between Bandai's SD lines come down to the level of detail, articulation, and customization options offered by each kit. Depending on your skill level and preferences, you can choose the line that best suits your needs.
