I would argue the other way around. Blood and Wine is fun and nice as a capstone to Geralt and has a lot of content if you just want to ride around and play Gwent and do the Wine Wars and play house with your vineyard or whatever. It’s a fun expansion with a lot of value for your money if that’s what you’re after.

Hearts of Stone though is the most focused, well written, cinematic and concise story and content they ever made for Witcher. Has great characters, mystery, tension, levels, cutscenes, atmosphere… For me it was by far the more impactful of the two DLCs. If anything B&W is too long, I was already burned out by the end of it.
