What will you mostly use it for?

Keychron J2 vs V1 Ultra: your questions
The most significant difference is the polling rate. The V1 Ultra offers an 8000 Hz rate in wireless and wired modes, while the J2 operates at 1000 Hz. The V1 Ultra also features a gasket mount design and includes a control knob, which the J2 lacks.
Yes. The V1 Ultra's product listing states it includes Mac and Windows keycaps and has a system toggle switch. It is listed as compatible with macOS, Windows, and Linux.
Yes. Both the Keychron J2 and the V1 Ultra feature hot-swappable sockets. This allows you to change the mechanical switches without soldering, supporting both 3-pin and 5-pin MX-style switches.
The V1 Ultra has a larger 4000mAh battery compared to the J2's 3750mAh. According to Keychron's description for the V1 Ultra, it can last up to 660 hours with the backlight off. A comparable runtime is not specified for the J2.
Yes, both can be customized via the Keychron Launcher web app. The J2 also supports the open-source QMK and VIA firmware directly. The V1 Ultra uses ZMK firmware, which is also configurable through the Launcher web app.
Both come with double-shot PBT keycaps. The J2 offers a choice between Cherry profile (shine-through) and MDA profile keycaps. The V1 Ultra comes with OSA profile double-shot PBT keycaps.
The 8000 Hz polling rate on the V1 Ultra is available in its 2.4 GHz wireless mode, according to the manufacturer. This theoretically offers lower input latency compared to the J2's 1000 Hz wireless polling rate, which may benefit competitive gaming.
Both keyboards are designed with sound-dampening materials. The J2 uses IXPE, PET, and EPDM foam layers. The V1 Ultra uses a gasket mount, EPDM foam, PET films, and other acoustic foams to reduce noise. Both should be reasonably quiet, with the V1 Ultra's gasket mount potentially offering a softer, more muted sound signature.
The V1 Ultra comes with screw-in PCB stabilizers, which are designed to be easily removed and replaced. The type of stabilizers on the J2 is not specified in the provided information, so modification may be less straightforward.
The J2 is offered with Keychron Super switches (Red, Brown, Banana). The V1 Ultra comes with pre-lubed Keychron Silk POM switches (Red, Brown, Banana). Both are available in linear, tactile, and clicky variants.
Yes. Both the Keychron J2 and V1 Ultra support a wired USB-C connection in addition to their 2.4 GHz and Bluetooth wireless modes. You can use them while charging.
The Keychron J2 is a strong contender for a first mechanical keyboard due to its lower price, hot-swappable design, and solid feature set including multi-mode connectivity. It allows you to explore customization without a high initial investment. The V1 Ultra is better suited as a first keyboard if your priority is top-tier wireless performance and a premium typing feel from the start.
