What will you mostly use it for?
The V3 Ultra is the more adaptable pick across office work, programming, modding and general productivity, thanks to its MX-style hot-swap support, firmware features and conventional layout choices. For gaming, the choice depends on whether 8000 Hz polling or magnetic-switch behavior such as Rapid Trigger and adjustable actuation matters more. The V3 Ultra is also the more clearly documented travel option, with its weight, dimensions and battery runtime specified. Both have wireless and wired connection options, so those alone do not separate them.

- The V3 Ultra specifies 8000 Hz polling, including in wired and 2.4 GHz modes.
- The NJ80 CP V2 HE has Rapid Trigger, adjustable actuation from 0.2 mm to 3.1 mm, and Dynamic Key Stroke for configurable key-trigger behavior.
