The paid for version does provide a few extra bells and whistles, but they may not be important to you.
I purchased Acronis True Image Home 2010 a few years ago now and for $23.99 it gave me incrementals, as well as the file and folder backup feature. In addition, it had the Try & Decide functionality which I used quite a bit at first, but now don't use as much...as I simply try everything in a VM.
If you are interested in file and folder backups and being able to do incrementals, it could very well be worth it.
Out of curiosity, what is the price for the paid version?
