Pros and Trade-offs

Your choice depends on which premium feature you value more. If you want a unique visual interface and the option for clicky switches or a barebones build, the RS2 V3 is the clear pick. If a sturdier aluminum build, advanced QMK programmability, and versatile tri-mode wireless are higher priorities, the RS2 4.0 is the better investment. Both are capable, feature-rich keyboards at a similar price point.
