I use the Hitfilm 3 Pro version. I like it in general.
But feels more like for hobbyists after a time. Not a bad thing of course.
My main problem is that i had some rendering problems. Blurry outputs...
Maybe just an error on my side or bad luck, bugs etc.
I will try to use the Hitfilm effects inside Sony Vegas then directly outputting from Hitfilm just because of this.
But it is free. Try and use it there are some nice features,effects.
