Pros and Trade-offs

Your primary need dictates the choice. If a thin, low-profile keyboard with layout flexibility for international users is your goal, the Keychron K5 QMK V2 is the clear pick. If you prioritize a premium, weighty typing experience with marathon battery life and a compact full-size layout for a stationary desk setup, the Yunzii AL98 is the better investment. Both are competent, programmable boards, but their physical designs cater to distinctly different preferences.
