Reel is very easy to use. It took me a few minutes to figure out how to create my first audiogram. The templates look very good and it's pretty intuitive to tweak and adapt. I transcribes my voice quite faithfully and it's not too much hassle to change and add the subtitles.
I got a free pro Headliner for a year but I prefer to use Reel. Basically it just works !
