Which is better for gaming?

The Corsair has the higher polling rate at 8,000Hz versus 4,000Hz wireless on the Razer. The Razer counters with hot-swappable switches and a command dial. Both are linear-switch boards, so pick on layout and price.

Which is better for typing and work?

The Corsair's 99% layout keeps a near-full key set and its low-profile switches suit long typing sessions. The Razer's 75% layout drops keys but saves desk space and adds the OLED display for system metrics.

Can I change the switches?

Only on the Razer. Its PCB accepts 3- or 5-pin mechanical switches. The Corsair's OPX optical switches are fixed.

Is the Razer worth the extra money?

At $199.99 low versus $116.99 for the Corsair, you pay about $83 more for hot-swap switches, the OLED display and PBT keycaps. Skip it if you mainly want wireless speed and macro keys.

Both use PBT or durable keycaps and aluminum or plate-mounted builds. The Razer's swappable switches let you replace worn switches; the Corsair's optical switches have no contact wear but cannot be replaced.

Does the Corsair work with a Mac?

Yes, Corsair lists Mac compatibility alongside PC. The Razer is listed for PC use.
