Would you rather fly BOS-ORD-HNL with the second leg on upper deck of newly configured C or...

BOS-IAD-SFO-HNL with IAD-SFO in F on a three cabin 777? The other two segments would be in domestic F.

Either way I'm purchasing the ticket and both are the same base price of $965 before tax. I have flown on upper deck of new C on LAX-SYD-LAX recently and do enjoy the new C but really haven't had the chance to sit in three cabin F in a while.

I guess other things to consider would be that this is during the Christmas holidays.

Please feel free to give your two cents! Or if you think another alternative is better!
