TSA has made publicly clear what has been anecotally clear, namely that if you do not move to a TTP, your % of PC selection will drop. Given that the actual $ cost of the various programs is pretty close, that the enrollment is good for 5 years, and that most employers who have people traveling will pay for it, GE seems to be the best deal. At $100 for 5 years, even if you only fly 10 round-trips/year, that's only $1 per checkpoint.
