The Ultimate Differentials

[Immmigrant]

I'm sure most of you guys have answered this question already but i'm looking into a LSD for my 96 240sx se. The problem is i can't come to a conclusion to which differential is better, Quaife torque biasing differential or Kaaz clutch-type LSD. I understand the Quaife uses helical gears and as they have on their website "The Quaife is extremely strong and durable and since the Quaife is gear operated, it has no plates or clutches that can wear out and need costly replacement." So does that mean clutch-type LSDs wear out faster???

Well this car is daily driven and in the future i might want to go drifting just a little bit.
