SU carb float bowl valves

I've run across two types of 'stock float bowl valves.
One is plastic shaft with metal seat and valve
'arrowhead'

the other is metal bodied shaft with a rubber 'arrowhead'
and metal seat.

Who prefers which and why?

I seem to be leaning towards the metal bodied
valve shaft that has the rubber arrowhead seat.
...seems like it would wear less and seal better
Thoughts?  anyone?
