Panels vs Display Suite


I am new to Drupal 8 and installing modules.

I have installed Panels but not enabled it and was thinking of installing Display Suite as well. Do you use just one of these layout modules or can you enable them both and use them both at the same time?

I was also wondering about installing Display Suite using Composer as I am not sure what to do about the space in the name.

I assume the right command is:

$ composer require “drupal/display suite: ^3.0”

but it could be:

$ composer require “drupal/display_suite: ^3.0”


$ composer require “drupal/displaysuite: ^3.0”

Does anyone know?

Thanks for any replies
