What will you mostly use it for?
The B39 is the more office-oriented choice, with its ergonomic Alice layout, quiet switches, macro keys, and knob. The K10 V2 has the edge for gaming and programming if you want a conventional mechanical layout and features such as N-key rollover and QMK. It also suits switch experimentation better when purchased as the hot-swappable version. For travel, the lighter and more compact B39 has the practical advantage, while content creators may prefer its dedicated macros and knob.

Keychron B39 vs K10 V2: your questions
The B39 is the more office-focused option, with an Alice-style layout and low-noise scissor switches. Its five macro keys and customizable knob also provide dedicated workflow controls.
The B39 uses a 96% Alice-style layout with a numpad, while the K10 V2 is a conventional 100% full-size keyboard. The B39 has a more compact arrangement, while the K10 V2 lists ANSI and several ISO layouts.
The B39 uses low-noise scissor switches, rather than the mechanical switches listed for the K10 V2. Keychron describes the B39's typing feel as mechanical-like.
Hot-swapping is available on the K10 V2 hot-swappable version, which accepts compatible 3-pin and 5-pin MX-style mechanical switches without soldering. Confirm the selected version, since the vendor also lists a non-hot-swappable option.
The B39's switches are soldered, so changing them requires soldering. It also takes low-profile switches only, not standard MX switches.
The K10 V2 is the more gaming-oriented choice if you want mechanical linear, tactile, or clicky switches, plus N-key rollover. Both listings include a 1000 Hz polling rate.
No, the B39 is listed without backlighting. The K10 V2 is available with RGB or white backlight options, depending on the version.
The B39 weighs 680 g, compared with the K10 V2 at 1160 g, and uses a 96% layout rather than a 100% layout. The B39 also supports Bluetooth, 2.4 GHz, and wired connections.
Both keyboards list Mac and Windows support. The B39 vendor description also names Linux compatibility, and the K10 V2 vendor description says its Launcher works with macOS, Windows, and Linux.
The K10 V2's north-facing LEDs can cause Cherry-profile keycaps to hit the switch housing. Its compatibility notes also warn that south-facing LEDs may leave shine-through legends dark or interfere with some sculpted keycaps.
Yes, the B39 has five dedicated M1-M5 macro keys and a customizable knob. Keychron says the macro keys can handle shortcuts, text snippets, app launches, or command sequences, while the knob can be assigned functions such as volume or zoom.
The K10 V2 is the stronger option for switch changes if you choose its hot-swappable version, and it supports QMK and Keychron Launcher. The B39 supports remapping and macro customization through Keychron Launcher, but its switches are soldered and its sockets accept low-profile switches only.
