What will you mostly use it for?
The CK68 has the edge for buyers who value its richer OLED description or want switch options beyond linear. The Spring Series is the more travel-oriented pick based on its lower listed weight. Modding is a close call because both are hot-swappable, though their listed switch choices differ. Both share the main connectivity modes and battery capacity, so those features do not separate them.
