Depends on what you are looking for. The Ouano is not a gold or double weave as far as I know. It is a very lightweight gi. Kinda like comparing apples to oranges. I don't have experience with the other gi's mentioned but thought I would drop my $0.02 about the comparison you are trying to make.
My instructor uses an atama gold weave (basic) and a mundial 7. The mundial 7 is alot lighter and thinner. I dont know the exact weights or how much it weighs compared to an ouano, but I do know that it is lighter than the usual gold weave.
