The best method for gathering a user’s permissions dynamically in Apex is to use the `Schema.sObjectType.User.fields.getMap().get('PermissionSet')` approach. This method leverages the schema's metadata to access the field definitions associated with the User object, specifically focusing on the PermissionSet field.

By retrieving the metadata dynamically, this approach allows the developer to programmatically inspect and use the available permissions without hardcoding values or relying on specific PermissionSet IDs or names. This dynamic access is particularly useful in situations where the Permission Sets may change over time or when dealing with multiple environments where Permission Sets might differ.

The alternatives provided do not offer the same level of flexibility or direct access to user permissions. For instance, querying the User object directly for PermissionSets does not provide a dynamic way of understanding the existing permissions associated with the current user context and can also be limited by the data returned from the query. Using `userInfo.getUserPermissions()` and global setting checks also focuses on specific checks without accessing the full range of dynamic permissions available to that user.
