What will you mostly use it for?
The RS2 4.0 edges ahead for office work and programming on the strength of QMK support, and it suits buyers who prefer a linear switch. The V2 is the more compelling gaming pick on the listed N-key rollover feature, and its lower weight favors travel. Modding depends on the kind of project: the 4.0 lists QMK, while the V2 is marketed as a DIY kit or barebones board. For content creation, the 4.0's aluminum case and larger listed battery capacity distinguish it.
