Csa Climate Battle: OR vs WA

Both WA and OR are dominated by Csb and Bsk climates, but both have a small corner of their state that falls under Csa or comes very close. Oregon's is in the southwest, and Washington's is in the southeast. So which corner has the better climate? I imagine that snow lovers will vote for Washington, and snow haters will vote for Oregon. But it will be interesting to see how much of a turn off Walla Walla's dark winters will be. I don't know about Medford, but I imagine it would be a lot sunnier since it's further south, and Walla Walla's winters are even darker than Seattle's!!
