Schools prep for the rides...the license is what counts..
The school matters mostly to you...in what it costs, how long it takes, how much crap you have to go through.
Fast and cheap is my modus...but exceptions exist when you have to leave school and now your the captain, right off the bat, there's the plane, passengers waiting...and you haven't even taken it up yet...
You might have the rating, but what you did in school will either prepare you to start flying, or they just prepared you to fly with someone else and start learning.
