Dell MS3320W
Score: 91/100
SteelSeries Prime
Score: 93/100Rankings

The SteelSeries Prime is a wired esports-grade mouse featuring the industry-leading TrueMove Pro sensor, magnetic optical switches and on-board customization. At 68 g it balances lightweight feel with a textured ergonomic shape, but its wired nature and heavyweight software may deter some users.

The Dell Mobile Wireless Mouse MS3320W offers exceptional battery longevity and dual-mode connectivity in an ambidextrous package, but its plastic build, lack of side buttons, and limited sensor performance keep it from appealing to power users.
