What will you mostly use it for?
The Flow Lite has the clearer edge for buyers prioritizing a gasket-mounted build, 2.4 GHz connectivity, a larger battery, or a dedicated volume roller. The K3 V2 is more flexible for layout selection and switch feel, particularly for people who need an ISO variant or want linear, tactile, or clicky options. Both can be used wirelessly or wired, and both require low-profile switches and keycaps. For gaming, the Flow Lite’s listed polling rate and 2.4 GHz mode are the more directly relevant differentiators, though the K3 V2 offers RGB lighting.
