#1, by far, is my preference... simply because the deflector seems much more a part of the "nose" elements of the hull in this case.
On the other hand, I like the slightly smaller deflector you used in the other version (or at least it LOOKS smaller... is that an optical trick?).
If it were me, I'd stick with #1 but make the deflector slightly smaller, more like the one you used in #2,#3.
But it's your baby... and the baby of the people in this particular "club" of course!
