Is there any reason to not go for the greatest gain antenna, given that
cost is not too important (within reason)?

Alligator effect. Wide mouth receiving everything.

"Alligator effect" normally refers to higher transmit power (not higher
antenna gain) -- big mouth, small ears.

If you don't need to
pickup everything then why bother? It just makes it harder for your WiFi
router to cut through all the noise of distant stations it doesn't
communicate with. ...

It actually usually makes sense, since higher gain means narrower
receive pattern, which better rejects off-axis interference.
Interference in exactly the same path is possible but unlikely.
