For outdoor survival stuff (like my avalanche beacon) they say you should only use the disposable ones. It’s probably got to do with cold tolerance or lifetime.
For Avalanche beacons you’re supposed to replace the battery after it gets below 95% charge.
I’d say it depends. For safety-critical stuff maybe, but for a headlamp or something I prefer rechargeable as I can easily recharge it from a power bank or a portable solar panel if needed. If you run out of a disposable battery for whatever reason, you’re screwed.
