Gateron Milky Yellow Pro V2 vs Gateron KS‑9 Yellow – Which One Should You Pick?

If you're deciding between two top-tier yellow linear switches, the Gateron Milky Yellow Pro V2 and the Gateron KS‑9 Yellow (also known as “Yellow Pro”), you're in for a treat. Both come pre-lubed and offer buttery smooth typing experiences—but they have some meaningful differences. Here's a side-by-side breakdown backed by hands-on reviews and community insight.

🔧 Technical & Feel Differences

• Housing & Wobble: The KS‑9 uses an improved mold with transparent top and white nylon bottom, resulting in notably tighter stem fit and reduced wobble :contentReference[oaicite:0]{index=0}. The Milky Yellow Pro V2, with its full-nylon milky housing, remains stable but slightly looser :contentReference[oaicite:1]{index=1}.
• Lubrication: Both are factory-lubed, but the Milky Yellow Pro V2’s nylon housing tends to dampen sound more, producing a deeper, quieter thock :contentReference[oaicite:2]{index=2}.

🎧 Sound & Typing Experience

• Milky Yellow Pro V2: Users describe its acoustics as “deeper, quieter, and more buttery” — great for those after a satisfying low-pitch thock :contentReference[oaicite:3]{index=3}.
• KS‑9 Yellow: Slightly brighter sound profile, with better LED compatibility (clear top, LED cavity), more suitable for RGB builds :contentReference[oaicite:4]{index=4}.

🗣️ Forum Feedback

> For some reason yellow pro is tighter (less wobble) than milky yellow pro… different molds. :contentReference[oaicite:5]{index=5}

> If you want the best sounding ones I would recommend the ks9 yellows… :contentReference[oaicite:6]{index=6}

> The Pros are a newer mold with tighter tolerances and come with factory lube. :contentReference[oaicite:7]{index=7}

> I’d probably recommend the Pros… they have updated, competent factory lubing. :contentReference[oaicite:8]{index=8}
