Best for

What will you mostly use it for?

The K1 Pro is the more flexible pick for wireless use, lighter carry, and buyers who need a non-ANSI layout. The S1 stands out for its CNC aluminum construction, steel plate, and support for additional keycap profiles described by Keychron. For gaming, the listed 1000 Hz polling rate and N-key rollover are shared, so the choice rests more on wired-only versus wireless connectivity. Both offer QMK, VIA, and hot-swappable versions.

For gaming

It's a tie

  • Both list a 1000 Hz polling rate and N-key rollover.
  • The K1 Pro can connect over USB-C or Bluetooth, while the S1 is wired only.

“I realy like this keyboard. I feel is harder to make typos compared to the K3 v2. I decided to go with the K1 Pro instead of the K3 Pro and it's going to to take time to adjust to the new layout, but the feeling and shape of the keys is definitely better.”
