I feel you! I switched from RPi4 4b 4GB to a 240 USD mini PC and the difference is astonishing. I no longer have "weird" crashed (e.g. with gphoto) every now and then that, I think, were related to RPi slowness.
The only regret I have is that now I'll never be able to use the StellarmateOS app! But I favor stability over everything else
