I would second the cautionary words from

Easier to transfer? No.
If you take NFO now, you need to go into the USN with the understanding that you will most likely never be able to switch back to being a pilot. I'm pretty sure I read recently on this website that there were only a handful of NFO's able to apply to Naval Aviator, and when I say handful, I mean less than 5 per year. Your scores are better for pilot than they are NFO, so if you want to be a pilot you might as well try for it now. Don't settle and regret your decision when you realize switching later is almost impossible.
Both SNA and NFO offer good careers, but don't pick one as an opportunity to apply to the other.
