I've heard nothing but horror stories on the Jetson & Tegra in general. I'd Avoid it unless the project MUST use a SoM w/ CUDA. which will basically only be Professional stuff. I've never heard of anything hobby level where a PCIe slot was a deal breaker- even with high vibration. (PCIe 4.0 isn't terrible difficult to get good flex cables for)

I hate my Jetson, and the hardware is fine for my purpose.
