What will you mostly use it for?
The K2 Ultra has the edge for buyers prioritizing compactness, lower listed weight, gasket mounting, or ISO-FR and ISO-IT layouts. The K8 Ultra’s larger TKL layout may suit those who prefer more keys in the main layout. Gaming is close on the listed polling rate and connection options, which are shared. For modification, the K2 Ultra’s mounting style and specifically itemized internal layers give it a more distinct specification profile.
It's a tie
- Both list an 8000 Hz polling rate and 2.4 GHz, Bluetooth, and wired connectivity.
- The K2 Ultra weighs 1084 g, while the K8 Ultra weighs 1299 g, a difference if keyboard weight matters for your setup.
