Can I use the global `strapi` or wrap all my services in a function receiving `strapi`?

For files like controllers and services,
both these methods seem to work:

module.exports = ({ strapi }) =>  ({
  doSomething: {
    strapi.log.info('ok');
  }
});

or simply

module.exports = {
  doSomething: {
    strapi.log.info('ok');
  }
};

Is there any benefit in using the function containing strapi? Is there any downside in using the global strapi?
