What's the difference between these two files?

[rjay100]

I've listened to both trigmorph and Bodytryout, both of which are by EMG. I know that the effects are similar, but what exactly is the difference? And which one is the better file?
I've tried both of them and have had no success with either but this is my first time trying hypnosis so it could be that. I've been trying to imagine and see myself but with a more muscular body but so far, not a whole lot. Thanks in advance for all of the help.
