What will you mostly use it for?
The Si75 HE has the clearer gaming focus, while the V6 Ultra is more suitable for buyers who rely on a numpad or want wireless connections. The V6 Ultra also has the broader path for conventional MX-style switch changes. For travel, the smaller 75% layout favors the Neo, although its wired-only connection is a limitation. Content creation depends on whether a full-size layout or layered key actions matter more.
Pick the Neo One of Zero Si75 HE
- The Si75 HE supports adjustable actuation points and Rapid Trigger through its magnetic switches.
- Dynamic Keystrokes can assign up to four actions to a key based on press depth.
- The V6 Ultra offers 8000 Hz polling in wired and 2.4 GHz modes, but its listed switches are conventional mechanical types.
