If you want to live in PDX, take the Brasilia and enjoy the huge QOL of living in base. You might have to commute to SFO/FAT for a month or two, but you will get PDX pretty quick. You will also get a line pretty quick compared to the jet, which means more days off and more pay. If the pay package goes through, you'll be making more than the jet guys for several years.
Commuting is awful, awful, awful. SJS is definitely not worth it. Spend your free days snowboarding/mountain biking/rock climbing or whatever it is you do in PDX instead of dealing with commuting BS. You will be a much happier person.
