you forgot and (align stack). And it's still not that simple, think about it...

Code:

if SOME_CONSTANT
  push 1
else
  push 2
end if

ESP based stack frames are incredibly problematic. A simple invoke will need to be "adjusted" if pushing from ESP. The only place suitable for ESP based stack frames is leaf routines that don't push/pop and don't call within themselves. As the programmer you must always be aware of what is happening to the stack and know how many items pushed/poped at every stage. It can be done with care but I think it is not worth the extra hassle unless you have a particularly good reason for doing it.
