Hello & Genealogy Software?

I came across this site when I was doing a search on Canadian WW 1 solders.  Looks like a great group and I'm looking forward to sharing with everyone.

I'm in Ontario, Canada and started researching my family about 15ish years ago.   Things were put on hold while we moved a few times.  But I've recently picked it backup.  I was wondering what your favorite genealogy software is?  Both free and paid. 
When I first started I was using Brothers Keeper, I think on DOS at the time. lol  I checked out the new version of it, but I don't really care much for it.
So I've been using Family Tree Builder and I'm going to try the free Legacy as well.  I have been thinking about buying the Family Tree Maker 2011 in the next few months.  But I'd love to hear your thoughts on the different programs available.
