Both are quality units. At the time when I got my Quaife, the prices were about the same, but Quaife had the advertised warranty, while Torsen's is implied. Both are equally strong units, with the Torsen having a slight higer biasing ratio.
But with the Quaife prices on the rise, the Torsen looks to be the better deal.
