One never runs out. The other actually gets used.
Verdict
A crank and solar radio cannot go flat permanently, which is exactly what you want from the one device that tells you whether to evacuate. Cranking is tedious enough that nobody does it for entertainment, and the internal battery still degrades over years. Buy the crank radio as the emergency device; keep spare batteries regardless, because a crank is a backstop rather than a primary power source.

You are building a kit that has to work after sitting untouched for two years. Solar keeps it topped up in a window and the crank gets you through a night regardless. Test it twice a year, because an internal battery that has never been cycled is the usual failure.

Losing heat is the most likely outcome of a winter outage, and hand warmers cost almost nothing and store for years. They are the cheapest item in a kit that meaningfully changes how bad a cold night is.

Far longer than the packaging suggests, often a minute of cranking for a few minutes of use. Treat it as an emergency backstop rather than a way of living.
Models with NOAA weather bands and an alert function do. Check the specification, because many cheap crank radios receive AM and FM only, which is not the same thing.
Top it up every few months and leave it where sunlight reaches it. Lithium cells left flat for years often will not take a charge afterwards, which defeats the purpose entirely.
