Bit of Detail here:
Kaaz vs Torsen Differentials | Magnus Motorsports
A plated LSD is stronger and more aggressive I would say. More predictable as well by its entire design. It would be an upgrade to what you have.
Not sure what the torsens are like in the wet, but once you break traction with a plated you want to ensure you're ready to be sideways and hold on. In the dry they are just as good.
Even going around a corner in the wet, a bit of boost and it's opposite lock time.
