Any high level thoughts regarding Radxa vs. RaspberryPi.
The only non RaspberryPi SBC that I've used was a version of the ASUS TinkerBoard, it was marginally better than the 3B version I had previously (latest one at the time).
RK3588 is a very powerful chipset. I have the 32GB version and it's great for running language models, as well as being my home server (Samba, PiHole...).
You need a recentish kernel with the Rockchip SoCs (I'm on Arch Linux running 6.10). Otherwise it works perfectly. I can give a strong recommendation.
