I tend to use Legacy Text more than Titles and Text as it has more useful (to me) presets and brings up some Windows fonts that don't appear in Titles and Text (a known bug).
A real good titler is still a big missing thing in Vegas. After several own attempts, I think Magic/Vegas creative Software left this part over to NewBlue....
Personally, I use most time Titles and Text and would like to see this Titler to be amended.
