For gamers looking to step up from entry-level gear without spending top-tier money, mid-range wireless gaming mice are the sweet spot. Two contenders often compared in this space are the Sharkoon SKILLER SGM3 and the Logitech G305. Both offer wireless functionality, customizable settings, and precision sensors—yet each takes a different approach to performance, design, and value.
Whether you’re an aspiring esports player or a casual gamer who wants low-latency wireless performance, this detailed face-off will help you make the right decision. We’ll evaluate both mice across ten essential categories: design, connectivity, sensor performance, battery life, customization, software support, weight and ergonomics, latency, value, and ideal use cases.
Let’s dig into which mouse wins where—and who should buy which.
1. Design and Build Quality
Sharkoon SKILLER SGM3
The Sharkoon SKILLER SGM3, Gaming-Mouse features a bold, angular design with a matte finish and RGB backlighting that gives it a distinctly gamer aesthetic. The mouse shell is robust and doesn’t creak under pressure. Buttons are responsive, and the grip feels substantial, especially for palm and claw grip users.
Logitech G305
The G305 follows Logitech’s more minimalistic design philosophy. With a clean, unlit exterior and a symmetrical shape, it feels versatile and can even double as a productivity mouse. Its plastic shell is high quality, and the build is surprisingly solid given its weight and price.
Verdict:
- Best for style and RGB lovers: SGM3
- Best for minimalists and ambidextrous use: G305
2. Connectivity Options
SGM3
One of the biggest advantages of the SGM3 is its dual-mode wireless and wired connectivity. It comes with a built-in lithium battery and a USB-C cable that allows for uninterrupted gameplay even while charging.
G305
The G305 is strictly wireless. It uses Logitech’s proprietary LIGHTSPEED technology for a 1ms report rate. While this is impressive, it lacks wired fallback—if your AA battery dies mid-game, you’re out of luck.
Verdict:
- More versatile connectivity: SGM3
- Faster dedicated wireless tech: G305
3. Sensor Performance
SGM3
It features a PixArt PMW3336 sensor with up to 6000 DPI. This is a solid, mid-range sensor offering decent accuracy, though not as flawless as more advanced ones in extreme FPS situations.
G305
The G305 uses Logitech’s HERO sensor, capable of up to 12,000 DPI. It delivers pinpoint accuracy, smooth tracking, and minimal acceleration, making it a favorite even among competitive gamers.
Verdict:
- Better high-DPI performance and accuracy: G305
4. Battery Life
SGM3
The SKILLER SGM3 includes a rechargeable 930mAh battery, offering up to 40 hours of use per charge with RGB lighting off. Charging is done via USB-C, which is fast and convenient.
G305
Logitech claims up to 250 hours of continuous use with a single AA battery. Real-world usage supports this claim, and the lack of RGB significantly extends life.
Verdict:
- Best for long-term battery without charging: G305
- Rechargeable and eco-friendly option: SGM3
5. Customization & Software
SGM3
The SGM3 supports customization via Sharkoon’s downloadable software, allowing for:
- DPI adjustment (5 profiles)
- RGB lighting configuration
- Button reassignment
- Polling rate control
The UI is decent but not very refined.
G305
G305 can be configured using Logitech G HUB, one of the best peripheral software platforms. It allows detailed button mapping, DPI settings, profiles, and surface tuning.
Verdict:
- Best software experience: G305
- More lighting control: SGM3
6. Buttons and Switches
SGM3
It offers 7 programmable buttons, which includes two side buttons, DPI toggle, and RGB control. Click feedback is crisp but not as snappy as premium mice.
G305
The G305 has 6 programmable buttons. Logitech’s mechanical switches are tactile, durable, and tested for 10 million clicks.
Verdict:
- More buttons and function diversity: SGM3
- Better click feel and switch quality: G305
7. Ergonomics and Weight
SGM3
At 110g, the SGM3 is on the heavier side, which suits gamers who prefer a sturdy grip. It fits medium to large hands well and feels premium but may fatigue during extended play.
G305
Weighing just 99g (and even lighter with mods), the G305 is a delight for FPS players who love to flick and move quickly. Its shape supports both claw and fingertip grip styles.
Verdict:
- More ergonomic for large hands: SGM3
- Lighter and better for fast-paced games: G305
8. Latency and Competitive Play
SGM3
Latency is good for casual to mid-core gaming but not as optimized for competitive play. The 1,000 Hz polling rate is respectable, but the sensor and wireless tech have slightly higher latency than Logitech’s LIGHTSPEED.
G305
LIGHTSPEED wireless gives the G305 wired-like latency. In blind tests, many players can’t distinguish it from a wired connection.
Verdict:
- Best for competitive FPS or esports: G305
9. Price-to-Performance Ratio
Both mice fall within a similar mid-range price category, but offer value in different ways.
- SGM3: Comes with RGB lighting, rechargeable battery, wired fallback, and more buttons—great for gamers who want aesthetics and versatility.
- G305: Prioritizes performance, battery life, and sensor quality—ideal for those who want pure functionality.
Verdict:
- Best all-in-one value: SGM3
- Best raw performance value: G305
