Is newer always better? In the case of education benefits for the military it might not be that way. It turns out that if you qualify for Montgomery GI Bill and Post 9/11 GI Bill you need to take a quick look to decide which is better for you to achieve your educational and career goals.
There is a great presentation on the VA site on how to figure out which program is right for you. For instance, Post 9/11 GI Bill does not cover OJT & Apprenticeship Training, Flight Training, Correspondence (this does not mean online institutions of higher learning), national testing programs, entrepreneurship training or co-op training. For those you have to use Montgomery GI Bill.
On the plus side for Post 9/11 GI Bill - you get a housing allowance and a book stipend which were not included in the Montgomery GI Bill.
When I started working with veterans looking to earn advanced degrees I assumed that newer would be better. But when you look at the details of the different programs, you really need to do a little research to make sure you are maximizing your military education benefits.
