Dont bother with the phantom.
Quaife has a lifetime warranty, the T2 doesnt. Though, I've never heard of somebody braking either part.
The Torsen is a 3 to 1 biasing ratio where the Quaife is a 2 to 1 ratio. As far as power rating, the Torsen would be good up to 400 or 500 whp while the Quaife even more - maybe to 700 or even 800 whp (according to Chris at Lentech).
