Your priority should guide this choice. If you want a keyboard you can deeply modify with firmware, macros, and different switches, the Keychron K5 QMK V2 is the clear platform. If you prefer a more straightforward, compact keyboard with a dedicated 2.4GHz dongle and a larger battery, and do not plan on modding, the Jamesdonkey S2 is a solid option. Consider the layout size difference, as the Keychron's full 100% layout includes a numpad the 96% Jamesdonkey does not.

“Genuinely happy with the keyboard. Had a low-profile one from another brand that has been used for 12+ years, and it degraded over time. This K5 feels very good. Still have to get used to the distance between the "primary," arrows, and numpad blocks, but…”
“Got this keyboard so I could keep my K5 Pro at work and this one at home. Both are the RGB version with brown switches, the K5v2 is quieter than the Pro and just as good to use. It also reports battery state over Bluetooth, which is a nice QoL improvement…”

Jamesdonkey S2 vs Keychron K5 QMK V2: your questions
The Keychron K5 QMK V2 has advantages for gaming. Its specifications list a 1000 Hz polling rate in wired mode, and it supports N-Key Rollover. It also offers a choice of switch types, including linear switches often preferred for gaming.
No, the Jamesdonkey S2 is not hot-swappable. Its vendor product page explicitly states "Hot-swappable: No." Changing switches would require desoldering and soldering, which is a more advanced modification.
Yes. Both keyboards list Mac and Windows support. The Keychron's vendor description further notes it includes keycaps for both operating systems and that its Launcher web app is compatible with macOS, Windows, and Linux.
The Keychron K5 V2 uses open-source QMK and VIA firmware, allowing deep, layer-based key remapping, macro programming, and community-driven customization. The Jamesdonkey S2's vendor description does not mention comparable advanced software features, focusing instead on 17 backlight modes.
The Jamesdonkey S2 has a larger 3000mAh battery compared to the Keychron K5 V2's 2000mAh. The S2's vendor claims up to 450 hours with backlight off, but real-world usage will vary based on connection mode and backlight use.
No. The Keychron K5 V2's case material is listed as a combination of ABS and aluminum. The Jamesdonkey S2, in contrast, is listed with an aluminum alloy case.
No. The Keychron K5 V2 only supports Bluetooth and wired connectivity. It does not have a 2.4GHz wireless mode. For a wireless connection on a PC without Bluetooth, you would need a separate Bluetooth adapter or use it in wired mode.
The Jamesdonkey S2 uses two-color injection-molded low-profile PBT keycaps. The Keychron K5 V2 uses shine-through ABS keycaps. PBT is generally more resistant to wear and shine than ABS.
The Jamesdonkey S2 is more compact due to its 96% layout, which omits some navigation cluster spacing. It is also slightly heavier at 600g, but its smaller footprint may be easier to fit in a bag. Both are low-profile, which aids portability.
The vendor description for the Keychron K5 V2 mentions redesigned stabilizers for less wobble, but does not specify pre-lubrication. The Jamesdonkey S2 vendor description does not provide details about its stabilizers. The Keychron's Milk POM switches are described as pre-lubed.
According to Keychron, the hot-swappable K5 V2 is compatible with Keychron Milk POM switches or Gateron/Keychron low-profile mechanical switches. The vendor explicitly states QMK does not support low-profile optical switches for this model.
