Surely the most common None vs non-None comparison would be the "is"
operator, which I hope remains fast.
I don't know about other people, but I often compare floats with ints.
Here's a contrived example:
x = some_float()
if x == -1:
return -2
else:
return (x**2-1)/(x+1)
I suppose it's no hardship to start writing float literals instead of
int literals, if needed.
