Superior salvage kits?

Has anyone noticed if superior kits are better than expert kits? I know the ID kits aren't worth the money. At cost per use, the superior kits don't seem worth the gold, but I'm wondering if you salvage more and better stuff using one? I've had a lot of good salvages since I bought one, but I don't know if I am just getting a lucky break lately or if it is consistent with everyone else's experience.

Searched and found these two

Thanks, I did a search but those didn't come up... guess I looked for the wrong thing.

And I've bought 3 superior kits already like a dope. Anet can I have my wasted 1200 gold back???
