If you're trying to compare these picks like a table in your head, use the same criteria across all of them. Weight and balance decide fatigue and stop-control. Shape decides whether your aim is repeatable. Polling rate is the nice to have that can turn into a battery tax—8000 Hz can be fun to test, but 1000 Hz is still the sane default for most players. Button count is a genre choice: FPS players want fewer, MMO and creator users want more. And software matters more than people admit: you want settings that stick, profiles that behave, and a DPI step that doesn't randomly change because you brushed a top button mid-fight.
A practical use-case: imagine you're playing Counter-Strike 2 on a high refresh-rate display, then switching to Helldivers 2 or a looter shooter with heavier tracking and more abilities. An ultralight like the Viper V3 Pro or Superlight 2 makes the CS2 side feel effortless—micro-corrections, quick resets, clean flicks. But when you jump to games where you're holding angles less and hitting utility more, something like a DeathAdder V3 Pro can feel steadier in palm, while the G502 X LIGHTSPEED lets you map grenades, push-to-talk, melee, and inventory without becoming a keyboard pianist.
The only time I push back hard is when someone tries to solve aim with specs. A mouse can't fix bad sensitivity choices, a worn-out mousepad, or a monitor that smears motion. If you're also shopping cheap computer monitors for gaming, prioritize a display with a refresh rate that matches your GPU reality, then set your mouse up for consistency: stable DPI, stable in-game sens, and a pad that supports your preferred glide.
