What will you mostly use it for?
The Q6 HE takes the lead for buyers prioritizing a full-size layout, wired 8K polling, and a gasket-mounted build.

Both offer magnetic-switch features and customization options, so gaming preferences depend on whether wired polling or wireless flexibility matters more. The Q6 HE also suits workflows that benefit from a numpad and knob.
