Incremental sync for Sql Server
What are you trying to "sync" exactly?  A subset of tables, the entire database?  Replication was designed for syncing data between databases and it offers a number of different flavors and features.  It's pretty verbose and should likely tackle just about any "sync" scenario you're looking to accomplish.  My main issue with Replication is that people often take it too far and try to use it as a fully fledged HA/DR solution when there are better approaches instead.

If you don't want to setup Replication (as it does have it's fair share of caveats and problems) and want to tap into Change Tracking or even CDC, then you'll likely be creating your own sync jobs/routines.  I'm not aware of any 3rd party tools that prefer Change Tracking or CDC over replication in this domain.
