Logitech MX Master 3S vs G Pro X Superlight 2

The Logitech MX Master 3S and G Pro X Superlight 2 both have Logitech's name on them, but they're built for opposite jobs, and two specs make that unmistakable. The MX Master 3S weighs 141 grams; the Superlight 2 weighs about 60 — roughly 60% lighter — because every gram is shaved for the fast flicks competitive gaming demands. And where the MX Master polls at 125 Hz (fine for a cursor), the Superlight 2 reports at up to 8,000 Hz, a 64-times-higher rate that shows up as lower-latency tracking in a shooter. Its HERO 2 sensor scales to 44,000 DPI versus the MX Master's 8,000. But the MX Master answers with everything the gaming mouse deliberately throws away. Its MagSpeed electromagnetic scroll wheel ratchets for precision then free-spins to fly through a thousand-line spreadsheet, it adds a dedicated horizontal thumb wheel and six programmable buttons, it clicks almost silently, tracks on glass, and uses Logitech Flow to move between a Mac and a PC. The Superlight 2 has five buttons, a plain notched wheel, and an ambidextrous shape — nothing to slow it down. Here's how to choose.
