What will you mostly use it for?
The EISA K686 HE leads for gaming and programming when a complete keyboard and magnetic-switch features matter. The COVE K733 is the more fitting choice for travel, calculator-oriented office work, and users who want a separate keypad with wireless connections. Modding also favors the COVE because it is hot-swappable, while the EISA accepts magnetic switches only. For content creation, the COVE's standalone calculator features offer a more specific numeric-work tool.
