Pros & Cons Side by Side

Corsair K100 RGB Mechanical Gaming Keyboard

OPX optical-mechanical switches at 1mm actuation — near-zero debounce delay
Dedicated iCUE control wheel for in-game macro execution and media control
PBT doubleshot keycaps — significantly more durable than ABS, won't shine with use
6-zone RGB with per-key lighting and AXON hyper-processing for smooth effects
Premium aluminium frame construction

Full-size keyboard with numpad — large desk footprint
OPX optical switches have a different feel to traditional mechanical — subjective
iCUE software is resource-intensive and required for full features

Corsair K70 RGB PRO Mechanical Keyboard

Full-size layout with numpad — the only gaming keyboard with dedicated numpad in this comparison
Corsair iCUE software syncs RGB with Corsair mouse, headset and fans for unified lighting
4-port USB passthrough hub converts single USB slot into multiple — practical desk organisation
PBT double-shot keycaps resist shine and yellowing after years of use
Choice of Cherry MX Red, Brown, Blue, Silent Red and Speed switches at purchase

Full-size takes the most desk space — less mouse movement room than TKL or 60%
iCUE software is feature-rich but resource-heavy — noticeable on lower-spec systems
No wireless option — USB wired only
