Both are awesome themes. I've owned both, but only TFTC remains. Tales is a little clunky, but it has everything you could want, excellent wizard mode, great ramps (possibly the best in pinball) drop targets, skill shot and even a captive ball shot. Not to mention some of the best dots in pinball and artwork that is spot on for the theme(it's ugly, it's suppose to be). The only downside is the poor audio sampling rate.
Creech has great artwork(its stunning) and excellent dots, but the ball does get lost behind the ramps and it only has a 2 ball multiball. Plus the hologram WILL eventually go blue then black and are impossible\expensive to replace.
