What will you mostly use it for?
The V6 Ultra leads in most desk-focused categories because it combines wireless connections, switch choice, and customization features. Its weight makes the K70 Core the more practical pick of these two when carrying the keyboard is a priority, although both are full-size. Gaming also favors the V6 Ultra on its listed wired and 2.4 GHz polling rate, while the Corsair remains an option for buyers seeking a straightforward wired linear board. Modders have a clearer reason to choose Keychron because its switches are hot-swappable.
