Pros and Trade-offs

Your primary need dictates the choice. If your workflow demands extreme portability, a unique ortholinear typing experience, and deep firmware-level customization, the Epomaker Luma40 is the compelling option. If you prefer a more traditional, feature-rich keyboard with a screen, knob, and longer battery life for a stationary desk setup, the Epomaker EA75 Max provides significantly more functionality out of the box.

+Ultra-compact 40% ortholinear layout saves substantial desk space.
+CNC aluminum case construction for a premium, solid feel.
+Full QMK and VIA firmware support for deep key remapping and macro programming.
+Low-profile design with a flat typing angle may reduce wrist strain.

+Includes double-shot PBT keycaps for greater durability and resistance to shine.

−Much larger and heavier (958.5g) due to its size, battery, and screen, making it less portable.
−Case is made from ABS plastic instead of metal.
−Software customization requires a wired connection to a PC, according to the manufacturer's specifications.
