I am a long time user of Legacy and gave no thought to FTM until I decided I needed an ancestry subscription and in effect FTM2012 came free. I installed it to have a look and was not hugely impressed until I went to the sources management screen - fantastic! and then places and media equally good. On the other hand reporting is very sparse with little control over the output, compared to Legacy.
Legacy v8 is due out sometime this year (probably) and I guess FTM2014 will be upon us soon, however, there has to be significant improvements before I will part with more cash.
I am currently using FTM because I have a load of sources to enter - and yes I should have done them properly to start with - but I am still dithering between Legacy and FTM
