Seattle's music scene is definitely more established and diverse, but Portland has a cool, indie vibe. Hiking is great in both, though the Cascades are more accessible from Seattle, while the Oregon coast is closer to Portland. Seattle is generally more expensive than Portland, especially for housing, and has seen increases in certain types of crime. Portland's cost of living is rising rapidly too, and it also faces challenges with crime and homelessness. Consider visiting both for a week to get a feel for each city's atmosphere.
