What's the difference between moa and mda?

Differences in appearance, scope of application and use effect.

1, appearance difference: the edge line of MOA keycap is smoother and more curved; MDA keycap is more square in appearance and shape.

2. Scope of application and use effect: MOA keycap is basically changed from the keyboard of QWERTY typewriter with high popularity, which is optimized for ergonomics, and will not hurt the neck or wrist after long-term use, and is relatively more suitable for users with long-term high frequency use; MDA is suitable for the traditional 104/ 108 film or wired keyboard, and can support all wired products on the market, but it is obviously not a good choice from the point of view of improving operating efficiency.
