I would like to know which diving certificate is the best, NAUI or PADI?

Question

Hello, I'm from Brazil and as both institutions are from the U.S, I decided to ask you guys which one shall I chose. I searched on the internet, but I just couldn't find any comparison between them. Oh, sorry about my english and thanks.

Answer 1

padi

Answer 2

They both will earn you your certification.  They are both internationally recognized.

There's no real difference between the two, other than some minor points.  

Go and talk to both instructors.  Check out both shops.  Pick the one you are more comfortable with.  It's that easy. :)

Answer 3

I was certified through NAUI, and from what I was told, there are a few differenes, but one isn't inherently better than the other.

NAUI is more conservative, less time underwater without entering Deco, slower ascent rate, etc.

NAUI also goes a little more indepth in training, meaning the course is a little harder, but I at least got a takehome test instead of a standard exam.

Either way, the instructor matters much more than the organization, pick one that you like and looks like he knows what he's doing.

Oh, don't take the weekend course, there's a reason crash courses are called that.
