I have used several genealogy programs over the past 20 years and without doubt The Master Genealogist is the best. It can print a wide variety of wall charts in sizes up to 3 feet by 30 feet !! It knows about A4, A3 etc. There is a UK version as well. It generates narratives that have sentence structures that can be left as the default or configured as you wish - very powerful. You can create new "tags" for events, I use one for bequests which is useful to show who left what to whom and strengthens the evidence of relationships.
The chart printing and reports are, however, only a small part of what it can do. The capability to hold multiple relationships such as parents (not sure yet which ones are "proven"), the source and surety of the evidence, location of the document (repository) are all invaluable. It also has the ability to hold exhibits (like scans of certificates) against an event as well as recording research tasks that need to be done.
I have no connection with Wholly Genes who produce the software but IMHO it is the only genealogy program worth using. I am also an IT consultant and the software is extremely stable, includes back-up routines and integrity checks and I have had no loss of data or corruption in 10 years of using it. My master database exceeds 15,000 individuals so it can take volume as well.
