Should I buy the Corsair K70 or Keychron V3 for typing and gaming?

For typing + gaming, I’d lean Keychron V3 for most people.

• Pick the Keychron V3 if typing feel matters most. It’s a better fit for long writing/coding sessions thanks to its hot-swappable design and QMK/VIA support, so you can remap keys and tune the layout more easily. It’s also still fine for everyday gaming.
• Pick the Corsair K70 if you care more about a gaming-focused board and prefer Corsair’s software ecosystem and features like dedicated media controls. Depending on the exact K70 model, it may also offer gaming-oriented extras like higher polling-rate options.

Short version:

• Best for typing: Keychron V3
• Best for gaming-focused use: Corsair K70
• Best all-around for mixed use: Keychron V3, unless you strongly prefer Corsair’s software and controls

If you’re comparing a specific K70 version, check the exact model name first, since K70 variants differ a lot in features.
