What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If you want keyboard-style commands with thumb-operated movement, the main distinction is whether you need analog key travel or a real thumbstick. Razer’s Tartarus V2 Pro combines analog optical keys with a TMR thumbstick; Azeron’s Cyborg II is built around configurable hand positioning and thumbstick movement. Neither is a universal pick: game input support, hand fit and setup matter.
This is a comparison of published specifications and a cited reviewer’s observations, not a hands-on five-product test. The available evidence does not support naming five verified products or ranking them as “best.”
What “analog” means on a gaming keypad
Two different kinds of control get described as analog. Analog optical keys detect how far a key is pressed, allowing input to vary with key travel. A thumbstick instead provides controller-style directional movement. They are not interchangeable: which one helps depends on the game and how it handles input.
- Analog key travel: Razer says the Tartarus V2 Pro’s analog optical switches detect key travel and can provide analog-style input.
- Thumbstick movement: Azeron says the Cyborg II can provide true 360-degree movement in games that support simultaneous mouse and controller input.
If you specifically want a proper directional stick rather than a D-pad, check that the model has a thumbstick and confirm that your game can accept controller and mouse input at the same time.

How the two documented options compare
| Model | Input and controls | Fit and configuration | Evidence and caveat |
|---|---|---|---|
| Razer Tartarus V2 Pro | Razer lists 31 programmable controls, analog optical switches, a TMR thumbstick, Rapid Trigger and adjustable actuation from 0.1 to 4.0 mm. Razer product specifications | Razer lists a fully adjustable wrist rest. Setup is through Razer Synapse; Razer support identifies the model family as RZ07-0552. Check software and firmware requirements for your OS and revision. Razer support | Specifications are manufacturer claims. A Windows Central review published October 3, 2026 reports one reviewer’s experience with comfort, layout and thumbstick; it is not a universal fit finding. Windows Central review |

Choosing between the Tartarus V2 Pro and Cyborg II
Choose based on the input you want
Consider the Tartarus V2 Pro if analog key travel is important alongside a thumbstick and a programmable keypad layout. Consider the Cyborg II if hand positioning, handedness and configurable sizing are central to your decision, or if your intended use depends on its thumbstick-driven movement. These are distinctions in published features, not a performance ranking.
Check game compatibility before buying
For thumbstick movement, verify that the specific game accepts controller input while you continue to use a mouse. Azeron explicitly makes its 360-degree movement claim conditional on simultaneous mouse-and-controller support. Do not assume every game or configuration handles mixed input the same way.

Check fit and setup
Compare hand-size guidance, handedness, finger reach, wrist or palm support, and available adjustments against your own setup. Manufacturer sizing information cannot guarantee comfort for every player. Also confirm the exact model, configuration, software support and OS or firmware requirements before purchase.
What about Azeron Keyzen and Cyro?
Azeron identifies Keyzen and Cyro product lines alongside the Cyborg family, but the available model-specific information is not detailed enough to compare or rank them responsibly here. Before considering either, check its current product page for exact specifications, hand orientation, intended role, software support and availability.

Why this is not a five-product “best” ranking
A five-way “best” list would imply five verified, comparable choices and criteria applied consistently. The available evidence establishes useful details for the Tartarus V2 Pro and Cyborg II, but does not verify enough about five qualifying models to support that claim. It also does not establish current regional stock, prices, warranty terms or marketplace listings, so none are stated here.
