What will you mostly use it for?
The EISA K686 Pro has the edge for gaming and programming if its stated polling rate or larger layout is a priority. The K708 is the more compact, lighter option for office use and travel, and its TFT display adds a customization feature for content-focused setups. Modding is a close call because both support hot-swappable switches, with different keycap materials listed. Each board keeps the shared tri-mode connectivity and gasket-mount design.
