The biggest drawback of going to Lakes in my opinion is the possibility of a failed training event. Is getting your time a month or two sooner really worth the risk of going through a program with a rather high washout rate?
I'll go ahead and say it: Looking back from where I am now, I didn't know my @$$ from a hole in the ground at 250 hours. I've always been pretty good at studying and memorizing things, so I very well might have been able to make it through their training with no problems... but holy crap that would have been sketchy. And not just during training either.
