I have North Sails on my J/30 "Toy Box" hull 324, and am very happy with both the performance and the longevity of them.
Lets look at what you are comparing, not apples to apples in what different Sailmakers are offering. I am a North Fan, and make no apoligy about it.
First, all but North, buys their cloth form a jobber, a manufacturer that makes and then sells their cloth to who ever will buy it.
Second, North is the only sailmaker that finishes their own cloth, they impregnate the resign in the cloth and then finish it off to higher standards then others.
Third, North is the only sailmaker that has two patients on the cloth they offer, the Radian cloth that is a true radian cloth(the true strength is in the length of the roll, while others offering you a Radial sail, that will not hold up as well) my boat neighbor shows me just what I am talking about, with blow-outs between each seam.
Performance the North Cross-Cut Mainsail has won more National Regattas than anything else. That said with the introduction of the North Radial Warp Oriented Main, I believe it will offer more performance due to the fact that with the radial design, the sail will offer less elasticity and you can get just a little lighter sail.
Not to Mention that the Mains built in New Orleans have been a consistent Regatta winner over time.
But if you are looking for a Durable non One-Design mainsail, the North 3Di would be the way to go.
This is what I believe, read and know, My two cents.
