KTT Purple Star vs. SP-Star Duck
An in-depth look at the KTT Purple Star and the SP-Star Duck switches—which one is the best fit for you?
Overview
When considering mechanical keyboard switches, two popular options to compare and contrast are the KTT Purple Star and the SP-Star Duck. The Purple Star stands out for its linear design, boasting an all-POM construction that provides a smooth typing experience with a neutral sound signature. This switch is ideal for light typists due to its very light 45g bottom-out, offering ease and comfort during use. On the other hand, the Duck switch offers a tactile typing experience with a subtle tactility that's perfect for those seeking a quieter option. With a clean and crispy sound profile, the Duck switch provides a polished typing experience. While the Purple Star is categorized as 'Mild', 'Low-pitched', and 'Easy-to-press', the Duck switch falls under 'Neutral', 'Mild', 'Buttery', and 'Polished' categories. Both switches have their unique strengths and cater to different preferences, so it ultimately comes down to personal preference. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the Purple Star and Duck keyboards offer distinct characteristics that cater to different preferences in sound profiles. The Purple Star's POM top and bottom housings create a deeper, muted sound profile, while the Duck's polycarbonate housings produce a sharper, higher-pitched, and crisper sound. This contrast in sound profile is attributed to the stiffness of polycarbonate plastic, which provides a clearer and more resonant sound compared to the softer POM material.
From an aesthetic standpoint, the choice of housing material can also impact the visual appeal of the keyboard. The translucent nature of polycarbonate makes it ideal for switches that incorporate RGB lighting, as it allows the lighting to shine through the housing for a vibrant effect. On the other hand, the opaque nature of POM may offer a more sleek and understated look. Ultimately, the choice between POM and polycarbonate housings may depend on the user's preferences for both sound and visual aesthetics.
While the Purple Star and Duck keyboards may differ in their housing materials, both options offer unique benefits that cater to different preferences. The split between the top and bottom housings of a switch allows for a varied user experience, as the bottom housing influences the bottom-out sound and feel while the top housing affects the sound when releasing a key. Whether you prefer the deeper, muted sound of POM or the sharper, crisper sound of polycarbonate, both options provide a customized typing experience that enhances the overall feel and sound of the keyboard.
Weight
When comparing the actuation force and bottom out force of the KTT Purple Star linear switch and the SP-Star Duck tactile switch, it is evident that the Purple Star is a lighter option with an actuation force of 43 grams and bottom out force of 50 grams, while the Duck is slightly heavier with a bottom out force of 58 grams. The actuation force of the Duck switch is unknown, making it difficult to directly compare to the Purple Star in that aspect. However, it is clear that the Purple Star offers a lighter typing experience overall. For those who prefer a more substantial typing experience with a stronger push feel, the SP-Star Duck would be the better choice. Ultimately, the decision between the two switches will come down to personal preference in terms of typing experience and weight.
Travel distance
The KTT Purple Star linear switch has a travel distance of 3.5 mm, while the SP-Star Duck tactile switch has a travel distance of 4 mm. In this case, the Duck has a longer travel distance compared to the Purple Star. The difference may seem minimal, but it can have an impact on user experience. The Purple Star's shorter travel distance may be preferred by gamers looking for quicker response times, while the Duck's longer travel distance may appeal to those who prefer a more substantial key press feel. Ultimately, the choice between the two switches will depend on individual preferences for travel distance and key feel.
