Voted Seattle, although I would miss the snow. Philly is meh.
Seattle does usually get some snow every winter.. not much but usually falling snow several times and accumulating snow at least 1 or 2 times. Obviously this varies. Some years see almost nothing while others will see 5 accumulating snows.
What you wouldn't see are the 1-2 foot dumps you get in Philly. But even then in 1949/50, Seattle got feet of snow and weeks of sub freezing weather. You just need the unusual combo of a very deep western trough that allows Arctic air to come in from the northeast and enough moisture from an onshore flow to dump the snow.
Barring that you can drive an hour or two to the Cascades where they literally get 500-800" of snow every winter.
