DOT 5 aka silicone fluid does not absorb moisture and is very good
for a car with excellent brake internals that you want to keep that way.
It also does not eat paint like DOT 3 or 4 will.

And Ken likes it because it's purple :-)

That said:
Silicone fluid will leak if your seals are at all worn. It will leak when
everyday fluid does not. It traps tiny tiny air bubbles that will give
you a soft pedal unless you are very patient about bleeding the
system. Some people never get the system to feel 'right'.

Castrol GT/LMA is a DOT 4 fluid that is very popular. Better than the
average DOT 3 but none of the drawbacks of silicone. A lot of us use
Castrol.
