Surely the only advantage of DOT5/silicone is that is doesn't attack 
paintwork, but it's disadvantage is that it is more compressible than glycol 
giving a spongier pedal.  Moisture will get into all brake systems 
regardless of fluid type, and it will lower the boiling point of all of 
them.  Because silicone isn't compatible with ABS generic car parts places 
like Halfords in the UK don't stock it any more, stocking just DOT4 and 
DOT4.1, the latter having a higher boiling point than DOT4 or DOT5, and less 
compressible than DOT5.  However it still attacks paintwork as far as I 
know.
