When you have a loose budget and are determined to buy a high-end gaming mouse , there are many options that you will find and many doubts. Today, we are going to make a technical comparison between the two best Razer gaming mice, the Basilisk Ultimate vs Viper Ultimate , both wireless and equipped with the same sensor but designed for very different purposes. Which of the two would be the most suitable for you? Let’s see it.
Both mice were introduced not long ago by Razer as their best bet for high-end gaming mice, and therefore all of Razer’s technology and experience has been painstakingly integrated into their designs and hardware, surely making up two of the best wireless gaming mice that exist.

All in all, there are some fundamental differences in its features and, of course, in its price , so it’s worth taking a deep look at this comparative technique to see which of the two best suits what you need. For reference, here are their sales prices on Amazon.
Razer Basilisk Ultimate vs Viper Ultimate technical comparison

| Price | € 169.99 | € 149.99 |
Both mice incorporate the latest-generation Razer Focus + optical sensor , with 20,000 DPI maximum sensitivity and configurable in steps of 50 to 50 DPI. According to the manufacturer, this sensor has a resolution accuracy of 99.6% even when operating in wireless mode, which guarantees that even the smallest movement is registered. They are equipped with intelligent tracking functions so that, in short, they are the most accurate that the manufacturer is capable of offering right now.

In both cases, Razer has used its optical switches on the main buttons, which use an infrared beam to record clicks allowing a response time of just 2ms. In addition, by not requiring physical contact, activation eliminates the need to integrate an anti-bounce mechanism, so there will never be involuntary pulsations.

As for the buttons, it should be mentioned that the Basilisk Ultimate incorporates 11 buttons in total compared to the 8 of the Viper Ultimate, being also one of them a trigger on the left side of the mouse that gives the user the possibility of choosing between two different ways, or delete it.
Following the technical comparison, the first differences are found in its battery, since the Basilisk Ultimate integrates a battery with a greater capacity, giving the device greater autonomy : up to 100 hours with the lighting off compared to the 70 hours of the Viper Ultimate . Speaking of lighting, they both have RGB Chroma of the brand configurable from the software, but the Basilisk has 14 zones compared to only 1 (the logo) of the Viper.
The biggest differences are in the design
So far we have seen that both mice use the same optical sensor and the same type of switches, so their technical differences are quite slim: just the battery and the number of buttons. However, if we go to value the design, the differences are much more substantial.
On the one hand we have the Viper Ultimate, a symmetrical and ambidextrous gaming mouse (valid for left-handed users) with buttons on both sides and that stands out for being one of the lightest wireless mice in the world, with only 74 grams having the battery. This allows much faster movements and is therefore ideal for FPS-type games and where there is frenetic action. However, with its number of buttons, it is not negligible for MOBA or even MMO games.

For its part, the Basilisk Ultimate is relatively heavier (107 grams), and its design is ergonomic for right-handers with thumb support. This mouse will be more comfortable for right-handed users who have palm-type grip, but not so much for users with claw-type grip or even fingertip. However, for these types of users it will be much more comfortable than the Viper Ultimate, which with its ambidextrous design is more “generic”.
The Basilisk Ultimate is therefore more designed for right-handed users, with palm-type grip, and who need more buttons but do not require too frenetic and fast movements, being therefore more suitable for general games, but not FPS (at least in compared to the Viper Ultimate, and this does not mean that it is a bad mouse for FPS, much less).

So which of the two is better?
Given that both have the same sensor and practically the same technical specifications, we cannot say that one is better than the other, but rather that one is better for one type of user and needs than the other.
Thus, we consider that the Viper Ultimate will be a better mouse for gamers of the FPS type and for users who have a claw or fingertip grip, while the Basilisk Ultimate will be the ideal option for users who have a palm grip, and for those who prefer the mouse for more general use, with all kinds of games (although of course, only for right-handers).
