What will you mostly use it for?
The V0 Ultra takes the lead for gaming, programming, travel, and modding, with its 8000 Hz polling, customization options, and smaller listed dimensions. The Retro18 suits office tasks that benefit from an integrated calculator and visible numeric display. For content creation, the Retro18's calculator functions offer a clear practical distinction, though the right choice depends on how often those functions are useful. Both are wireless, hot-swappable numpads, so the major trade-off is purpose-built calculator convenience versus the V0 Ultra's customization and build features.
