^How about getting promoted twice and maxing out the pay scale?
There is no 'best' commissioning program. Each one has its pro's and con's, and it's really up to the individual to determine what they want to try for. The best that you can do is maximize your profile for whichever respective board will consider you. In other words, find something that you want, stick to your guns, and be the absolute best that you possibly can.
Speaking as someone who fell by the wayside on the long road from commissioning to wings, it's not always about being NPQ'd or not up to putting the time and effort in. In some cases (I like to think myself included), you can have all the heart and drive in the universe and just not measure up. Sometimes, it just ain't in the cards, but that doesn't necessarily mean it's from a lack of effort/committment.
I realize heyjoe did, in fact, say that the vast majority were for the aforementioned reasons, and that he was not implying that all were due to that. And while I'm setting the record straight, let me just add the following: Judging from what I've seen dealing with aviators from ALL type/model/series, the TRACOM made the right decision in my case, because I would have fucked it all away eventually. Like I said, sometimes it just ain't in the cards.
