Block Suites provide you with a set of various blocks for your posts and pages. They are all bundled into a single plugin. You can have more than one collection installed. As always, make sure you test them for plugin conflicts with existing plugins. For your post you can mix and mash blocks for different plugins. It’s actually quite cool.
ACF Blocks is built on-top of Advanced Custom Fields Pro. This plugin requires ACF Pro to function correctly.
