Housing materials
In comparing the housing materials of the Gateron Milky Red Pro (KS-3) and the SP-Star Polaris Purple, the main difference lies in the material used for the housing. The Milky Red Pro (KS-3) features a nylon top and bottom housing, which gives it a deeper and fuller sound profile due to the softer nature of nylon. On the other hand, the Polaris Purple utilizes a polycarbonate top and bottom housing, resulting in a sharper, higher-pitched sound profile thanks to the stiffer nature of polycarbonate. While both materials have their unique characteristics, the choice between the two ultimately depends on the desired sound experience for the user.
In terms of aesthetics, the housing material also plays a significant role. The translucent nature of polycarbonate used in the Polaris Purple provides a clear housing that allows for RGB lighting to shine through, enhancing the overall visual appeal of the switch. In contrast, the nylon housing of the Milky Red Pro (KS-3) does not offer the same level of transparency, which may appeal to users looking for a more understated look. Whether it's a preference for a clear, colorful housing or a more muted appearance, the choice between nylon and polycarbonate can greatly impact the overall design of the switch.
Despite the differences in housing materials, both the Gateron Milky Red Pro (KS-3) and the SP-Star Polaris Purple offer a unique typing experience that caters to different preferences. While the nylon housing of the Milky Red Pro (KS-3) provides a softer and more absorbent typing feel, the polycarbonate housing of the Polaris Purple delivers a crisper and more resonant sound. Ultimately, whether you opt for the deeper sound of nylon or the sharper sound of polycarbonate, both switches offer a high-quality typing experience that can be customized to suit individual preferences.
Weight
The comparison between the actuation force and bottom out force of the Gateron Milky Red Pro (KS-3) linear switch and the SP-Star Polaris Purple tactile switch reveals some significant differences. The Milky Red Pro has a lighter actuation force of 45 grams compared to the Polaris Purple, which doesn't have a specified actuation force. In terms of bottom out force, the Milky Red Pro requires 52 grams, while the Polaris Purple has a heavier bottom out force of 67 grams. This makes the Milky Red Pro a lighter option overall, which may be preferred by those who type for longer periods or engage in extended gaming sessions. On the other hand, the Polaris Purple offers a more substantial typing experience for those who prefer a stronger push feel. Both switches offer distinct advantages depending on individual preferences, with the Milky Red Pro being lighter and the Polaris Purple being heavier for those seeking a more robust typing experience.
Travel distance
Both the Gateron Milky Red Pro (KS-3) linear switch and the SP-Star Polaris Purple tactile switch have a travel distance of 4 mm, making them equal in this aspect. This means that when pressing down on a key with either of these switches, you will experience a consistent 4 mm travel distance. This makes them both ideal choices for those who prefer a shorter travel distance compared to switches with longer travel distances. Overall, whether you choose the Milky Red Pro or the Polaris Purple, you can expect a similar key feel and actuation experience due to their identical travel distances.
