Metalogix Content Matrix - Great and Easy Tool to Use On-Premises
What do you like best?
Interface is easy to use, with a classic 2 window style where you can separate your source and your target. There are a variety of connections that can be used, which are important if you want metadata to be saved during the migration. There is also mapping available for fields and users and a lot of other things. The options are easy enough to learn quickly, and the copy modes are intuitive as well so you know what you are trying to copy or migrate.
What do you dislike?
Migrating to SharePoint Online is really slow. It took a vanilla site of less than 1 GB a full day to migrate. It could be because the connectors being used to connect to the cloud are outdated, but I am not 100% sure.
Recommendations to others considering the product:
Content Matrix is a great and easy to use tool for migrations on the on-premise SharePoint environment. It is a great tool for backup and restore as well.

We used this tool to copy content from lists to sites from one site to another. This is a very flexible tool and was mostly used for achiving.
