That depends on whether or not you're too comfortable with apache. nginx is far more light weight, I don't use apache at all, everything is nginx for me. you will have to run php-fpm though, as nginx does not have internal language support for php.

Well should I migrate to nginx from apache2 ? Have to take care of small DigitalOcean droplet with one wordpress & mysql

If you have any q's or issues with apache, nginx, or servers in general, hit me up. Been working with servers, linux, etc for the past 15 years :)
