What will you mostly use it for?
The KB 40 has the clearer feature advantage for gaming, office use, programming, modding, and content creation, based on its hot-swap sockets, VIAL support, and additional layout and mount options. Travel is a closer call: both are compact 40% keyboards, but the KB 40’s listed 1000g weight may matter to buyers carrying a keyboard regularly. The Contra remains a more straightforward kit, though changing its soldered switches requires soldering.
Pick the Kezewa Niu Niu KB 40
- The KB 40 has hot-swap sockets, unlike the Contra’s soldered switches.
- Its aluminum case and gasket mount are specified alongside an FR4 plate.
- Neither product lists RGB, so lighting is not a differentiator here.
