Pros and Trade-offs

Your choice comes down to aesthetics and connectivity. Choose the Keychron K3 Max SE if you prefer a lighter, naturally styled keyboard with 2.4 GHz wireless and extensive internal foam for a quieter sound. Choose the Keychron K3 Pro if you need a specific ISO layout, prefer a heavier metal build for desk stability, and value south-facing RGB for keycap compatibility.
