Which is worse?

I can never decide which is worse, waiting to O or the 2WW. For me, waiting to O is highly unpredictable. Stress seems to screw things up even more. It can happen as early as day 16 or as late as day 60. This keeps life interesting because finding time to BD with a husband who works irregular hours and a little Daisy Bud running around is quite difficult.
On the other hand, the 2WW is much more predictable. It's always 15 DPO that AF arrives. Resisting the urge to POAS too early is hard and so is over analyzing every possible pregnancy and/or AF symptom is enough to drive me crazy.
What do you think is the worst?
