Do not listen to the hype on Kent. It is indeed a suburban hellhole. You'd only live there if it was the only place you could afford to buy a house.
Better choices: Columbia City or West Seattle. When you look at buying, you may look south of WS at White Center--it's an up and coming neighborhood. Ditto South Park, weird but cool. Most of SP is under the airport flight pattern so that's a consideration.
Don't let anyone tell you the Federal Way is a good idea either. If you're moving to Seattle, you want to enjoy Seattle, not live in faceless suburbs.
