Seattle does have warmer and drier summers than London definitely. Also, despite the fact that London and Seattle are about the same temperature on average in the winter, Seattle can get colder weather from time to time than London can due to Britain being an island and more moderated by the Gulf Stream. From a gardening perspective, you can grow more tender and subtropical plants in London than you can in Seattle (i.e. Canary Island Date Palms will grow in many parts of the UK including London but will not grow here in Vancouver or in Seattle unprotected.)
I would argue that England is more likely to have colder winters than Seattle actually. Definately this one just gone, an average temperature of 33f, when was the last time Seattle had a month that cold.

I've looked at the averages, and it seems Victoria BC is nearly spot-on with London's average temps.

Which leads me to believe that the role of Gulf Stream is somewhat overrated as there is no equivalent of Gulf Stream near PNW.
One difference, though, is that oceanic influence in Europe penetrates much farther inland than in North America but that is due to mountains (Cascades, Rockies).

Not the Rockies, but certainly the Cascades. Eastern Washington (east of the Cascades) has a dramatically different climate from Western Washington. Western Washington is very mild and very damp. The Hoh Rain Forest gets 150 inches of rain a year (12 feet), while Yakima gets roughly 8 inches (about the same as Tucson Arizona) and is a desert.

Eh, I think some marine influence is still felt even east of the Cascades. Boise, Idaho is much milder in winter than, say, Minneapolis despite being at a higher elevation. Even Helena, Montana is not as cold as one might expect it to be at 4000ft elevation and 46 degrees North Latitude.

Yeah, that's true. Having lived in Eastern North Dakota I can attest to your statement.
Chinook winds only reach as far east as far western South Dakota which explains the 20 degree difference ( many times) between high winter temps in Rapid City and central South Dakota.

the coldest month ever December 2008 - average mean temperature 36.9F. Average high only 40.8 and average low 33.0

Some interesting stats I found...
Seattle's record low temperature is 0F (-17.8C) on January 31, 1950. I'm not sure what the record low in London is but I'm willing to bet it's above 0F and definitely on the south coast of Britain it's much warmer than that.
Some other interesting stats I found for Seattle
Max number of days where temperature stayed below freezing: 10 (January 21 to January 30, 1969)
Max number of days where night time temps were below freezing: 24 (December 23, 1946 to January 15, 1947)
Vancouver also had a particularly cold month in January 1950. In fact, I believe it was the coldest January on record here. It had an average high of only 26.7F (-2.9C) and an average low of only 14.5F (-9.7C) which makes for an overall average of 20.6F (-6.3C).
Even recently, the winter of 2008-2009 which was one of the snowiest on record for Vancouver had 3 solid weeks where temperatures stayed below freezing and some of the outer suburbs of greater Vancouver recorded temperatures as low as 5F (-15C).
