No difference for me. What matters is how comfortable I was on the flight and how well, or whether, I slept. Getting off a 12 hour flight*, east or west bound makes no difference, it's adjusting to the time-zone difference after arrival that is the kicker. I find arriving in the morning then forcing myself to stay awake until the normal clock time (not body clock) for going to bed is the best approach. Incidentally, I found that it worked on my SYD-LAX-JFK flight which arrived in the late afternoon. It arrived in LA early morning so I treated the transcontinental flight as part of the 'staying awake all day' regimen.
One thing that Qantas is experimenting with on their long-haul research flights is how they manage time changes on flights. Rather than serve a meal then turn the lights off at the start of the flight, then turn them again shortly before arrival for another meal, they are telling people to change their clocks as they board, then run cabin activities to match time of day at the destination. They've flown JFK-SYD and LHR-SYD so they're covering both directions.
* I find that if you can deal with 12 hours, extending it to 14 or 16 hours makes only a marginal difference.
