If you want one keyboard that does everything right out of the box without needing to mod it, the Keychron Q5 Max is the answer. It's the board enthusiasts recommend to friends who don't want to go down the custom rabbit hole.
“The Keychron Q6 or Monsgeek M5 are about the most endgame you can buy in stock.”
