It's going to depend mostly on your travel pattern. I also consider DL miles pretty worthless, but 60,000 is worth, at a minimum, a last minute domestic flight. If you ever find the need to take one of those, the miles will come in handy.

Seems like you are more interested in a US-Asia trip, however. If you haven't already, try looking at partners like Korean and Malaysian. Also try searching starting in cities other than SFO. I think they now fly from SEA, PDX, and of course cities in the midwest and east coast. An unconventional routing may not show up in the award calender, even if it is available.
