Pros and Trade-offs

Your primary need dictates the choice. If your workflow demands a numpad, you value a screen and knob, and the keyboard will live on one desk, the TH99 Pro is the more practical and feature-rich option. If you crave maximum portability, want to experiment with an ortholinear layout, and value open-source firmware customization, the Luma40 is the unique and compelling pick. Consider your willingness to adapt to layers versus your need for immediate key access.
