Welcome to the sharks.
Goodness NO! Portland is a terrible place, who would want to come here? Seattle is the place for you. While it does rain, its usually only just a mist (aside from November through June

).
Portland, who would ever want to live in Portland? Its fly over country from everywhere, hardly a destination!
However, if you love liberal politics, Portland and Seattle are constantly one-upping each other, so its a push in that regard. Oregon has a state income tax, one of the highest in the nation, and high property taxes too. Washington has sales tax (also high, but you only pay when you buy, not simply when you earn) however Seattle itself just voted for an city income tax (though it has little chance of holding up in the courts).
I lived in Seattle area 25 yrs, now Portland. I like Portland better.
