Questions and answers

Which is better for typing and office work?
The Corsair K70 CORE SE, because the numpad and full-size layout suit spreadsheets and data entry. The Razer types well too, with a softer gasket feel, but you give up the numpad.
Which is better for gaming?
The Razer BlackWidow V4 Pro 75% wins on paper: 4K Hz wireless polling, hot-swappable switches and a command dial for macros. The Corsair is still a solid 1,000 Hz wired board with full NKRO.
Which lasts longer?
Corsair rates its MLX Red v2 switches to 70 million keystrokes, and the wired design has no battery to wear out. The Razer's hot-swap socket means you can replace worn switches instead of the whole board, but its battery ages over time.
Is the Razer worth stepping up to over the Corsair?
Yes if you want wireless, a compact footprint, an OLED display and the ability to change switches. No if you mainly want a full-size wired board and don't care about those extras.
Can I use the Razer with a Mac or console?
It is listed for PC use. Bluetooth lets it pair with other devices, but Razer's software features like the dial modes and Chroma lighting are built around Windows.
Do both have PBT keycaps?
Yes. The Razer uses doubleshot PBT and the Corsair uses dye-sublimated PBT. Both resist shine better than ABS, though doubleshot legends cannot wear off.
