Yes, but what is the difference (in gain terms) between one that looks
flat and one that looks pointy?


Assuming equally efficient feeds, nothing.

It is diameter in wavelengths that determines gain.

Changing the "pointyness" just changes the focal point, which may cause
gain problems due to practical problems with providing a decent feed, but
doesn't change gain.
