Anyone running a gripper diff in their road car ?

Basically can't make my mind up between a gripper or a quaife.
I know the gripper will need a rebuild at some point and can be snatchy at low speeds but is the best for track work.
The quaife doesn't need rebuilding but doesn't give the 'ultimate' grip but is good.
Price wise they are about the same after machining.
Need to know as my box goes in next week for a rebuild.
What do you think?

I have ran a quaife in other cars on track and road could not fault them best thing I have ever bought on cars. My mate runs a gripper in his and it's alittle rough
