Pros and Trade-offs

Your primary layout need dictates the choice. If you want arrow keys and a function row in a 75% form factor with ISO support, the Mysterium is the clear pick. If you prefer a more compact 65% board where deep QMK programming is a priority, the Discipline is the better route. Both are challenging soldering projects suited for experienced builders.
