Thank you, and what you say is completely fair. The Keychron K3 is an excellent keyboard and certainly gets the job done for many people. I would actually argue Altar II is excellent value at $249, especially when you consider the materials, special components, and scale we are at.
Altar II is quite a quiet keyboard, and there is a special sandwich of materials specifically designed to make it as quiet as possible.
The built-in speaker is interesting. Really it's just there because it's fun, and its nice to get the odd bleep or chime when your keyboard connects or begins charging.
