Short answer: It depends on what you value. Both are high-quality, but they shine in different ways.

How they differ (quick overview)

• Origin and style: ROYCE' is a Japanese brand best known for ultra-smooth, fresh “Nama” ganache-style chocolates and delicate flavors. Ghirardelli is an American/Californian company known for firmer chocolate bars and squares, bold dark chocolate, and widely used baking products.
• Texture: ROYCE' (especially Nama) is famously creamy and melt-in-your-mouth. Ghirardelli is firmer with a satisfying snap for bars and a denser bite for squares.
• Flavor profile: ROYCE' tends to be subtle, refined, sometimes lighter and more milk-forward or with delicate inclusions (e.g., matcha, alcohol-infused). Ghirardelli often has stronger cocoa/roast notes, especially in higher-percentage darks.
• Ingredients & freshness: ROYCE' often emphasizes fresh dairy and ganache, so some items have shorter shelf life and a fresh, luxurious feel. Ghirardelli focuses on shelf-stable bars and baking chocolate with consistent flavor and long availability.
• Variety & availability: Ghirardelli is widely available in many U.S. stores and online; it also offers a broad range of baking products and chocolate formats. ROYCE' is less ubiquitous (available in specialty stores, airports, or online), so it can feel more boutique or premium.
• Price: ROYCE' products typically cost more per ounce than mainstream Ghirardelli items, reflecting artisanal style and imported status.
• Best uses: ROYCE'—gifting, tasting, indulgent fresh truffles or Nama. Ghirardelli—everyday treats, baking, melting for desserts, and strong dark chocolate cravings.

Which is “better”?

• For a luxurious, ultra-creamy, delicate experience (and you don’t mind paying more or seeking out the product): ROYCE'.
• For a bold, reliable chocolate for snacking or baking that’s easy to find and generally more affordable: Ghirardelli.

Products to try if you want to compare

• ROYCE': Nama Chocolate (original or matcha).
• Ghirardelli: Intense Dark Squares (60% or 86%) and their milk chocolate caramel squares.

Bottom line: Neither is strictly “better” for everyone — choose ROYCE' when you want a decadent, fresh confection and Ghirardelli when you want firm, cocoa-forward chocolate or something reliable for baking. If you’re unsure, try a small package of each side-by-side.
