I use // when it's an afterthought -- a function I want to apply after  
everything else, especially if I'm likely to remove that step, a bit later.

I use f@something when f has a single argument and "something" is simple.  
Cos@x, for instance, but Cos[x+1]. In both cases, I'm using fewer  
keystrokes than Cos[x] or Cos@(x+1).

I mix operator forms to avoid deep nesting of brackets, to the point that  
the human eye can't tell what function is applied to what.

But, by all means, do it any way you like!
