Oh for real I'd take London weather any day rather than MSP weather.

No context. Minneapolis is "hot like hell" in summer and "cold like hell" in winter.

London is mild and rainy but it's not too bad.

Latitude isn't everything. I grew up on a latitude that is probably relatively uninhabitable in Canada.

Seattle is pretty mild compared to most of the northeast. Seattle, and heck, even Ketchikan, have milder winters than Minneapolis. My experience in Seattle is fairly similar to my experience in Lausanne, except the latter was further south and had a bit more snow.
