What will you mostly use it for?

Keychron C3 Pro vs V3 Ultra: your questions
Yes, according to the specifications, the C3 Pro is hot-swappable. This means you can change its switches without soldering, allowing for easy customization of the typing feel.
No, the V3 Ultra does not use VIA. It is powered by ZMK firmware and is programmed through the Keychron Launcher web app, which provides similar functionality for remapping keys and macros.
The C3 Pro is a wired-only keyboard with a Type-C connection. The V3 Ultra offers much more flexibility with wired, 2.4 GHz wireless, and Bluetooth 5.3 connections.
The V3 Ultra includes a 4000mAh battery that can last up to 660 hours with the backlight turned off. The C3 Pro does not have a battery as it is a wired-only keyboard.
The C3 Pro uses ABS keycaps (specifically OEM profile shine-through double-shot ABS), while the V3 Ultra uses PBT keycaps (OSA profile double-shot). PBT is generally more resistant to developing a shiny surface over time.
Yes, the Keychron Launcher web app allows you to remap keys and customize macro commands, shortcuts, or key combinations to enhance gaming or work efficiency.
The Keychron C3 Pro uses plate-mounted stabilizers. The Keychron V3 Ultra uses screw-in PCB stabilizers, which are generally more stable and less prone to wobble.
Yes, the V3 Ultra is designed for both macOS and Windows. It comes with a system toggle and an additional set of customized keycaps for both operating systems.
The Keychron V3 Ultra supports an 8000 Hz polling rate in both wired and 2.4 GHz modes. The Keychron C3 Pro has a 1000 Hz polling rate.
Yes, the V3 Ultra includes a knob. The vendor notes it is available in a 'Fully Assembled Knob' version, suggesting a rotary encoder for volume or other controls.
The C3 Pro offers three levels of adjustable typing angle: 4 degrees, 6 degrees, and 8.7 degrees. This provides more ergonomic flexibility compared to the V3 Ultra.
The V3 Ultra is generally better for modding. It has a polycarbonate plate, screw-in stabilizers, and multiple foam layers (sound absorbing foam, PET film, EPDM foam, bottom case acoustic foam) that are easier to replace and customize.
