Our Verdict

SteelSeries Apex 3

Corsair K55 RGB PRO XT

The Corsair K55 RGB PRO XT and the SteelSeries Apex 3 are non-mechanical gaming keyboards with comparable performance. The Corsair has significantly lower latency, individually-lit keys that are independently customizable, and its companion software has onboard memory, but you can't sync settings to the cloud. On the other hand, the SteelSeries has ten zone RGB backlighting, but the keys aren't individually backlit. That said, it feels sturdier, it has a wheel on the top right, and it has more stable keys that offer a better typing experience than the Corsair.
