I don't think a tiny bit of easier working with it is why lead based would be used in aerospace ;)

Shininess? Who cares.

Now I know nothing about which is better in these regards but:

What would you look for in aerospace applications?

I would imagine things like:

Proneness to cold joints. Ease of detecting cold solder joints. Longevity (in general). Longevity under the stresses of aerospace realities. Etc.

Do you have data on that?
