Here are my thoughts
Teaching
Etreme burn is much longer than Prophet and Richard Sanders teaches many differebt variations to do the visual change, eplaining in depth each one of them . He also discusses what to do with different currency and goes many times over all of the moves and the construction of the gimmick making it really easy to follow along.On the other hand prophet is short and the constructin of the gimmick is covered in less time and also much less ways to change visually the bills are shown.Furthermore, when teaching the moves he doesnt show them as many times as Richard does.
Gimmick
Extreme burn and Prophet use almost identical gimmicks. The main difference is that Sanders uses another small object to help him (which is provided with the purchase of the dvd.Again Sanders goes into more details about the construction of the gimmick than Tom does.
These are the main differences you should consider since they look pretty much the same to the audience it is up to you to decide. I would choose extreme burn although it lacks the T11 music.
