No, the Ajazz AK820 Pro does not have a joystick. It features a metal knob for media control. The Epomaker RT85 includes a dedicated joystick that controls volume, mutes audio, and toggles RGB effects.

The Epomaker RT85 offers a choice of linear, tactile, and silent switch options from the factory. The Ajazz AK820 Pro specifications only list linear switch options, such as the Ajazz Gift, Flying Fish, and Dreamy switches.
The Ajazz AK820 Pro is more portable. It is lighter at 810g compared to the RT85's 1000g, and it is slightly shorter in length (327mm vs 360mm), making it easier to pack.
Yes, both feature per-key RGB backlighting with south-facing LEDs. South-facing LEDs are often preferred as they improve compatibility with Cherry-profile keycaps and reduce glare.
The Epomaker RT85 product listing specifies a 1000Hz polling rate in both wired and 2.4GHz wireless modes. The Ajazz AK820 Pro listing also states a 1k (1000Hz) polling rate in wired and 2.4GHz modes.

The Ajazz AK820 Pro mentions sound dampening and a flex-cut design but does not specify the number or types of foam layers.
The Epomaker RT85 features an adjustable kickstand that offers three fixed typing angles: 5, 6.7, and 10 degrees. The Ajazz AK820 Pro does not list an adjustable kickstand feature in its provided specifications.
