What will you mostly use it for?
The Rainy75 Pro has the edge for gaming, office work, programming and modding, mainly through its listed polling rate, firmware support and ISO option. The AK820 Pro is the more convenient choice for travel because it weighs much less, while both retain 75% layouts and wireless connections. For content creation, the AK820 Pro's display and media knob offer visible controls the Rainy75 Pro does not list. Both are hot-swappable gasket-mount keyboards, so neither is short on the core enthusiast features.
Pick the WOBKEY Rainy75 Pro
