What will you mostly use it for?
The Keychron K3 V3 wins in most mobile and tech-focused categories due to its wireless design, low-profile form, and superior programmability. It is the clear choice for travel, office use with multiple devices, and programming. The Ducky One 3, as a wired-only board, finds its strength in stationary setups where its acoustic tuning is a priority. For gaming, the Keychron's specified high polling rate gives it an edge, while content creation is a tie, dependent on preference for layout versus software features.

Ducky One 3 vs Keychron K3 V3: your questions
The Ducky One 3 has specific sound-dampening features, including a silicone plate dampener and EVA foam case dampener, which are designed to reduce noise. The Keychron K3 V3 also includes IXPE, EPDM, and latex foam layers for acoustics, but its low-profile switches may produce a different sound signature. For the quietest option, the Ducky offers Cherry MX Silent Red switches.
The vendor descriptions do not specify console compatibility for either keyboard. The Keychron K3 V3 works with Windows and macOS. Its wired USB connection may function with some consoles, but this is not guaranteed by the provided information.
Yes, the Keychron K3 V3 is hot-swappable, allowing you to change switches. However, the vendor states it is only compatible with Keychron Milk POM or Gateron/Keychron low-profile mechanical switches. The keycaps use a low-profile LSA profile, which requires specific low-profile keycap sets for replacement.
The Ducky One 3 vendor description does not mention any companion software for RGB control. The listing confirms it has north-facing RGB LEDs, but how they are controlled (likely via onboard key combinations) is not detailed.
The Keychron K3 V3 uses the Keychron Launcher web app for key remapping and macro creation. This is enabled by its support for QMK and VIA open-source firmware. You connect the keyboard via wired mode to a web browser to access the customization interface.
