This comparison is for buyers deciding between a high-end, fully-featured keyboard and an ultra-portable, minimalist one. The decision is difficult because both offer hot-swappable switches, gasket mounts, and VIA programmability, but they serve opposite ends of the size and functionality spectrum. The Chilkey ND104 is a premium full-size board packed with extras like a screen and modular components, while the Epomaker TH40 is a tiny 40% board focused on saving desk space and being travel-ready. Your choice hinges entirely on whether you need a dedicated numpad and function row or are willing to use layers for everything.

Your primary need dictates the choice. If you require a full numpad, dedicated function row, and premium materials for a stationary setup, the Chilkey ND104 is the superior investment. If saving desk space or having a keyboard that fits in any bag is your top priority, and you are comfortable with a layered 40% layout, the Epomaker TH40 is a capable and more affordable option. Consider how often you use arrow keys, numbers, and function keys without holding a modifier key.
The Chilkey ND104 is the clear choice for stationary, productivity-focused tasks like office work, programming, gaming, and content creation, thanks to its complete key set and premium features. The Epomaker TH40 wins decisively only for travel, where its minuscule size and light weight are paramount. For modding enthusiasts, the ND104's superior materials and internal construction provide a more rewarding foundation for customization.
