Are there major differences between OSB brands?

I have a choice of several brands for what I need, GP, Weyerhauser, LP, and something branded as Roy o'Martin. Any one of these better than others or are they all basically the same. I tried googling and got nothing except for some complains about Norbord brand and a page that claims all brands except one (doesn't say which) leak air right through the OSB.

I'm just curios if anyone knows whether some companies use better glues/processes in making theirs than others or if one brand is known to be better.

Considering you have to maintain a 1/8" gap between sheets.....yea, air is going to get past it.
