Best for

What will you mostly use it for?

The Q3 Max has the edge for office work, programming, modding, and creator workflows, where its ISO variants, QMK support, and knob offer specific benefits. The Lumino75 is the more compact pick for travel, with its 75% layout and larger battery. Gaming is a tie on the listed polling rate, while switch choices and N-Key Rollover differ. Both include south-facing RGB lighting, so shine-through legends remain dark on either board.

For gaming

It's a tie

  • Both list 1000 Hz polling in wired and 2.4 GHz modes.
  • The Q3 Max offers N-Key Rollover and switch options including linear, tactile, and clicky; the Lumino75 listing specifies linear Astral switches.
