Portland has some major advantages over SF, but as someone who also goes there regularly (~5 weeks/year), I still prefer living in SF at the moment. Not considering the amount of tech jobs there (which is a major factor for me), the city in general just isnt quite there yet. There are also some very major fiscal problems that have to be sorted before I'd consider moving.
Great place though, definitely might end up there one day
