How much experience do you have using wp-cli? Drupal/drush are a long long way off perfect but comparing drush to wp-cli is apples and oranges.

wp-cli is extremely brittle even for very simple download+install, produces very poor defaults in terms of file/directory permissions and general on-filesystem stuff, and this is before you get into things like drush's many other functions for general admin or its extensibility.

That is not a criticism of wp-cli's developers though, as about 99.9% of its limitations are down to the Wordpress core team's complete disinterest in accommodating its functionality well or in providing a codebase that fits into a modern deployment setup in any reliable, well-considered way.

The work done on wp-cli is really commendable: it seems to be battling against quite a tide.
