rewrite or return for simple redirection

[neubyr]

I am trying to understand which option would result in more efficient HTTP
redirection. I am trying to redirect ^/address page to ^/contact page.

Option 1:
rewrite ^/address /contact permanent;

Option 2:
location ~ ^/address {
  return 301 $scheme://$host/contact
}

Which option should be preferred? Both options involve regex and I am not
sure which one will be faster. Are there any other better options?
