FTM is an average,run-of-the-mill genealogy program with quite a few limitations and gripes; but that has one giant feature over its competitors - it is the gateway into the ancestry.com databases via merging records with your file - sometimes for whole families at a time (eg US census 1880 and after).
Ancestry is great in the area of censuses, birth and death records, civil war records, WWI draft registrations and other areas; but weak in real estate deeds and probate records and wills.
There is no comparison of FTM to the capability of the online trees. FTM has refinements and capabilities far beyond the on-line ancestry trees. Including filtering, places management, and reporting. It is well worth the price to get it over the ancestry tree capability.
