Our Verdict

SteelSeries Apex 3

Corsair K55 RGB

The SteelSeries Apex 3 and the Corsair K55 RGB are both full-sized gaming keyboards with rubber dome switches. The SteelSeries has a sturdier-feeling build quality and keystrokes that require less operating force. The Corsair has substantially lower latency, and though its keystrokes require a higher operating force, they also have better tactile feedback, although that can tire your fingers more quickly.
