NGFB uses your existing content to generate meta tags and Schema markup — there's no need to manually enter / configure any additional settings or values, but if you want to, you can customize just about anything and everything. ;-)
NGFB creates complete and accurate social meta tags and Schema markup — including the usual titles, descriptions, hashtags, and images, but also videos, e-commerce products, author profile / authorship, co-authors, publisher information, ratings, event details, recipe information, and much more — all from your existing content.
NGFB provides special support and optimization features for Pinterest — offering customized Pinterest image sizes and avoiding conflicts between incompatible Pinterest and Facebook / Open Graph meta tag values.
NGFB includes advanced quality control checks and features — verifying minimum / maximum image dimensions and aspect ratios, checking the webpage for duplicate meta tags, showing warnings for missing and required images, and theme header template validation for suggested markup.

Additional Free extension plugins are also available for WPSSO, including two different types of sharing button extensions:

New features are added, tested, and released incrementally, instead of grouping them together in a major version release. When minor bugs fixes and/or code improvements are applied, new versions are also released. This release schedule keeps the code stable and reliable, at the cost of more frequent updates.
See release early, release often (RERO) software development philosophy on Wikipedia for more information on the benefits of smaller / more frequent releases.
