Pros and Trade-offs

Your priority should guide your choice. If you value a deeply cushioned, quiet typing sound, ultra-long wireless battery life, and a dedicated gaming dongle, the Epomaker TH108 delivers. If you need a slimmer keyboard, require extensive key remapping and macro support via QMK/VIA, or need a specific ISO layout, the Keychron K5 QMK V2 is the superior tool. Both are competent wireless full-size keyboards, but they serve distinctly different user profiles.
