the reason i like ngsec, is because it is free, and like i said, it's for yourself to see how much you've advanced, and although many questions probabely can be solved with google, the challenges can not, these are:
one windows app to crack,
one linux app to crack,
two sql injection pass throughs,
one data decipher,
don't know how you will google for that, if you do, please let me know, since it took me a lot of time solving them :D
so, yes i disagree, not totally, but still a bit :)
