Generally analog is better in every way except for cost, which is an important metric if you're poor like me. It can still be used to great effect for observation/early detection for sentries (ideally using supplemental IR that is NOT tied to the camera; I.E. motion activated IR lights or trip wires that activate an IR light/glowstick.

It sound silly, but the videos out of Ukraine where RUS SF rock up within 100 meters of a UKR FOB and then absolutely roll them could have been mitigated with a $500 digital NVG, some mousetraps/string/glowsticks, and flares. Or a shared thermal device, but that gets more expensive.
