What will you mostly use it for?
The Mysterium suits buyers who want ISO support or a 75% layout, and its FR4 switch plate is a useful kit distinction. The Discipline is the more compact option and the only one of these kits with explicit QMK support. Both require soldering for switch replacement, so neither is a quick-swap choice. Gaming comes down to layout preference rather than a stated performance advantage.
It's a tie
- Both are wired DIY kits with soldered switches.
- The Mysterium is a 75% layout, while the Discipline is a 65% layout, so the choice depends on the layout you prefer.
