Location vs. rewite

I want to server favicon from a different place rather than the root
folder.
As I explored I have two options

location = /favicon.ico { alias /var/www/media/images/favicon.X.ico; }

rewrite ^/favicon.ico /var/www/media/images/favicon.X.ico last;

As I understand the second one needs an additional regex check for every
request to check if the url is favicon or not (imagine that we have a
rewite
of ^/(.).(.) and thus the favicon rewite must be first).

How the location works? Does it also should be checked on every request?

In general, which solution is better ?

This is wrong - you can rewrite to other location, not to path on file
system.
Anyway rewrite does not need here, use location.

Sorry, my bad! In the second case, I meant rewrite ^/favicon.ico
/media/images/favicon.X.ico last;

but anyway, it seems that location works better in general.

Yes, location is better and even faster in general.
