Pros and Trade-offs

Your primary need dictates the choice. If you want a thin, lightweight keyboard for travel or a desk setup where low height is critical, and you value deep programmability with QMK/VIA, the Keychron K3 Pro is the clear option. If you prefer a more traditional, acoustically-tuned typing experience with a gasket mount, pre-installed sound-dampening foams, and don't mind the extra weight, the Akko 5075B Plus offers better value for modders and those seeking a premium feel.

Akko 5075B Plus

+Gasket mount structure with a polycarbonate plate for a flexier, cushioned typing feel.
+Comes with multiple pre-installed foam layers (IXPE switch pad, silicone plate foam, case foam) for enhanced acoustics.
+Includes ASA profile double-shot PBT keycaps and additional themed novelty keycaps.
+Larger 4500mAh battery capacity for longer wireless use between charges.
+Offers knob support for additional functionality.

−Heavier at 1500g and bulkier, making it less portable.
−Case material is plastic/ABS, lacking the aluminum frame option of the K3 Pro.
−Vendor description lists a 3000mAh battery, conflicting with the 4500mAh spec, causing uncertainty.

Keychron K3 Pro

+Ultra-slim, low-profile design with an aluminum frame option for a premium, portable build.
+Native QMK and VIA support via the Keychron Launcher web app for extensive key remapping and macros.
+Includes low-profile double-shot PBT keycaps and is compatible with Gateron low-profile mechanical switches.
+Vendor highlights three levels of adjustable typing angle for ergonomic support.
+Well-reviewed with a 4.7/5 average from user feedback.

−Significantly smaller 1550mAh battery capacity.
−Limited to Gateron low-profile mechanical switches for hot-swapping, reducing switch compatibility.
−The vendor notes a 90Hz polling rate in wireless mode, which is lower than the wired 1000Hz rate.
