The 405 cuts right through classic L.A. culture exports like the Valley, Bel Air, Santa Monica and eventually the O.C. while the 10 passes through the heart of the city climaxing in the best panoramic view of downtown - and both are legendary for their traffic; trust me, you haven not truly experienced bumper-to-bumper, painful, want to end-one's-life traffic in your lifetime until you have enjoyed a rush hour trip on either of these main arteries of the city. It's also the greatest source of free parking in West LA.

Ultimately, I think you have to choose the 405 because when you finally crawl over the the top of the hill heading south from the Valley into the main basin of Los Angeles, the view of the region is spectacular... and you'll have plenty of time to appreciate it because you'll be moving at no more than 5 mph an hour. There's nothing more L.A. than that!
