Weather is one of those things that everyone complains about, everywhere.
The only way to properly evaluate weather is to (a) figure out what you like, and (b) check the data on Weatherspark. Unless you're talking about the summit of Mt. Washington or Ben Nevis, the complaints will always be scarier than the reality. Take Seattle's notorious cloud cover and rain. Reality: 80% cloud cover in the winter, meaning 15-20 hours of sunlight per week-- not great, but not "constant overcast"-- and an hour or two of light rain on most days. Complaint: "you never see the sun in January and it always rains".
It's unpredictable how someone will react to climate (especially because even specific locales have good and bad summers and winters from year to year). I've lived in Minnesota and New York City, and I always had worse winter SAD issues in New York, not because of anything to do with the weather itself, but for the damn buildings. "Urban sunset" is 2:30 in some neighborhoods, in the winter. (That said, the benefits of living in New York more than make up for it.)
London's definition of "hot" is 20-25 C and mostly sunny. Personally, that's all the heat I need, but there are people in the US who hate the lack of a "real" summer (30+) in places like Seattle, London, or Paris. Most of the US, even in the North (Chicago, New York) gets summers that are very hot by European standards, and so some people get bothered when it's July and they have to wear a jacket in the morning. I don't. When I was in L.A. a year ago people were complaining about "June Gloom" because it was 22 C and cloudy. I couldn't believe it; I was like, "June is still spring, this is awesome!" It was probably a bummer to people who thought LA had year-round "beach weather", though.
