Razer BlackWidow V4 X Yellow
Score: 90/100
RK Royal Kludge R75
Score: 88/100Rankings

The BlackWidow V4 X (2023) is a full-size wired keyboard that combines ultra-fast 8000 Hz polling, per-key RGB, six macro keys, and quiet linear Yellow switches with a premium aluminum build. It delivers top-tier performance but is heavy, lacks USB passthrough, and depends on Razer software.

The RK Royal Kludge R75 is a wired 75% keyboard that blends a gasket-mount, multi-layer foam dampening, hot-swappable switches, and a removable CNC aluminum volume knob. It adds onboard memory and vibrant RGB while retaining a compact footprint.

Products in the top-left offer the best value (high score, low price).

Professional reviewers gave the keyboard a consistent 4.0/5.0, highlighting its fast actuation, high polling rate, robust build, and rich RGB features while noting the slightly hollow case tone and the absence of a USB passthrough.
Everyday users generally praise the keyboard's quiet linear feel, striking RGB lighting, useful macro keys, and comfortable magnetic wrist rest. However, a notable minority report premature key failures, out-of-the-box defects, and dissatisfaction with Razer's support, as well as the typical ABS keycap shine over time.

“Very quiet and smooth for office and gaming use”

“RGB looks stunning, especially with underglow synced to other devices”

“Macro keys are a game-changer for MMOs and productivity”




Professional reviewers highlight the R75's thocky typing feel, premium gasket mount, and the value-packed removable volume knob, calling it a well-rounded budget-friendly board.
Users love the satisfying typing experience and the knob, but note occasional spacebar wobble and uneven RGB lighting.
