Jim Stopanni's workout is not really your average workout. If you follow his program to the T, be prepare to vomit. Its a lot on your cardio. And WHEN the average joe gets huffing and puffin on this high intensity, they'd drink a lot of water but what they don't realize is, without controlling your water intake, (since you'd be over drinking), you will be induced to vomit.
All the active rest between sets is gonna pretty much empty your energy very fast.
Kris Gethin's DTP workout is great for the avg Joe or even slightly advanced who wanna try something different. For slightly advanced, may wanna skip the first few weeks because it is meant to get the avg joe started.
DTP works on high intensity and volumes. It is great for hypertrophy but not everyone agrees with it. If you follow it to the T, you will get serious soreness. Its going to failure (ie unable to complete a full rep after 50+ reps); then you are to go further by cranking out another 20-25 partial reps. But the program wont have you do that EVERY day. It is quite smart actually. On DTP workouts, you will realize that the week will only have 3 days of weights training. You get plenty of rest (due to the intensity of the DTP).
The 20min cardio before and after (you can switch out separately) and the introduction of 150 twists after several starter weeks. If you are religiously following EXACTLY what the program provides (including the nutrition), yes I bet you will cut. That is a hell decent amount of cardio for cutting purposes. 40minutes a day and almost every day of the week.
Also, by following the workout EXACTLY means that you do not switch up the order of exercise. For legs day example, KG's workout load up front with quad extensions, curls etc before he hits you with squats. This is his principle of hitting your legs at several specific angles before ending the workout with a compound squat after the fact that your legs are already tired. Whereas other muscle groups, he will order it with the large muscle group exercise (some call it for sizing,) and then end with isolation.
In addition, you have to follow the nutrition plan. If you see his workout program nearing the end, like the 11th and 12th week, its 3-4 days of workout only per week, and the workout is lighter. This is because you are suppose to be on a steep carb deficit. This is akin bb'ers cutting towards 2 weeks out of their competition. Following the nutrition plan is probably the biggest kicker in the series although I must say that, his DTP principle can create mental blocks for lifters. For example, on a 50,40,30,20,10 pyramid down. You mind can set yourself to hit MAX beast mode at the 10rep set. BUT since DTP reverses the pyramid after it comes down, ie; 50,40,30,20,10,10,20,30,40,50 reps, UNLESS you do not know about the entire set and goes beast mode on the 10rep, you will be likely to use ***** out on the 10, and maybe push at weights at 70% of your potential, because you KNOW the pain of going back up the 50 reps. Thus, this said, you may not be challenging your strength.
Lastly, KG's workout is a 3-4 day split, thus although the workout looks lengthy on some days, it is actually working 2 muscle groups, something similar to push/pull splits. Thus, you will get 4-5 and as low as 3 exercises for each muscle groups. This is great for beginners.
So in brief, I'd say KG's 12week cutting DTP is nice and caters to a wide group of people whereas Stopanni's is a bit on the advanced side.
Eitherway, if you look at the entire program (instead of just watching the video), assess the program and see if you can follow through. Don't go into it all excited only to half ass and going through the motion. If you are really novice, I'd even recommend the ladies program for anyone, ie Jamie Eason's program.

not kidding!
You overanalyze too much. =P
