What will you mostly use it for?
The K2 Pro wins for gaming, office, and programming due to its robust build, higher polling rate, and deep QMK/VIA customization.

For content creation, it is a tie; both keyboards offer multimedia keys and wireless freedom, but they satisfy different needs for desk space and customization.

“I have been using the keychron K2 V2 for more than a year so when this came out, I knew I had to get this. and boy I never imagined the smoothness and thock on this thing. I replaced the brown switches with lavender purples and it feels even better.”

“I had a full-size mechanical keyboard before that was tking too much of deskspace. This keyboard with it's 65% size is amazing and saves quite some desk space.”
“Non-rgb version feels nice, but the battery is killing the whole experience... Even with the lights turned off, i can't get the keyboard to work on battery longer than 3-4 days, which is super annoying and not making me trust into this brand. Especially if…”

Keychron K2 Pro vs K3 V2: your questions
The K2 Pro is far more compatible with custom keycaps. It supports standard MX-style switches, allowing you to use almost any aftermarket keycap set. The K3 V2 uses low-profile optical switches with a proprietary stem, so its keycap options are limited to specially designed low-profile sets.
No, only the Keychron K2 Pro supports QMK and VIA software for custom key remapping and macros. The Keychron K3 V2 does not mention QMK or VIA support in its specifications.
The Keychron K2 Pro has a significantly larger 4000mAh battery compared to the K3 V2's 1550mAh battery. This means the K2 Pro should last much longer on a single charge, especially with the backlight off.
No, they are not interchangeable. The K2 Pro uses standard 3 and 5 pin MX-style mechanical switches. The K3 V2 uses low-profile Keychron Optical switches, which the manufacturer states are not compatible with any conventional MX-style switch.
The Keychron K2 Pro is better for quiet environments because its hot-swappable versions include sound-absorbing foam and a silicone dampening pad. The vendor description also notes pre-lubed switches for smoother and quieter operation.
Yes, both keyboards are explicitly stated to be compatible with both macOS and Windows. Both include keycaps for both operating systems, and the K2 Pro offers a Mac multimedia keys layout.
The K2 Pro uses a steel plate, sound-absorbing foam, and screw-in PCB stabilizers for a more solid feel. The K3 V2 focuses on an ultra-slim design with a streamlined aluminum body but lacks the internal dampening and heavier construction of the K2 Pro.
Yes, both keyboards support wired (USB-C) and wireless (Bluetooth) operation. You can switch between them as needed, and both can connect to up to 3 devices via Bluetooth according to the K2 Pro's description.
The K2 Pro offers three levels of adjustable typing angle (5°, 9.2°, and 12°) for more ergonomic support. The K3 V2 has a simpler two-level adjustable rubber feet for changing the angle.
The K3 V2 may be simpler for a beginner due to its focus on a slim, ready-to-use design. The K2 Pro offers more advanced features like QMK/VIA customization which could be overwhelming, but its hot-swap capability makes it easier to try different switches without soldering.
