I would personally prefer a much more predictable climate, where you are always guaranteed to get a lot of good weather throughout summer months and sports events etc, don't get rained off. Either a Mediterranean climate as in Southern Europe, or a continental climate, where you get hot summers and really cold winters. I don't really understand why (judging by reading threads on some other sites, anyway), a lot of people seem to like the British climate which is similar to Northern France, Holland etc, but given that it's an island, probably even worse. There seem to be a lot of people who like UK weather because they absolutely hate summer if not even slightly warm weather. TBH I find that a really weird/annoying opinion, don't get it at all! Though I'm probably unusual in not really caring about the famous green of the British countryside, which a lot of people like. A brown landscape as in Southern Spain means more water supply stress, of course.
I would never want to live in Northern England or Scotland (used to know Scotland well), because the climate is definitely cooler and wetter up there. Recently it was apparently only 33F at the site of a big regional television transmitter in Northern England, while one of the coastal cities in the South West was 69F. When the sun does come out and it gets decently warm/hot for a while, as it admittedly did for long periods earlier this year, then it is nice. Yes it can get oppressive sometimes (especially in London) because it's usually humid heat (not dry heat as in some countries), but personally I don't care much or have any particular trouble sleeping in the heat. Just now it's mostly been warm and a bit humid but overcast for a long time, and unfortunately isn't really forecast to get much better. Not that the flies mind, they are a total pest in my bedroom right now.
As for winter, at least in certain places up North, you may well still get some proper regular snow for a while, especially in parts of Scotland. That is very rare in the South nowadays, perhaps because of climate change. Most winters in the past few years have just been endlessly mild with low cloud, not that much sun, and more rain than in summer (at least in the South East). It's true that there isn't the danger of tornadoes, hurricanes etc, here. But the weather in New York or Washington, for example, sounds much less boring. The temperatures in Britain tend to be too low, there are not enough thunderstorms, and though it can happen, you hardly ever get a hailstorm. The recent strong autumn-like winds were annoying, but apparently unusual at this time of year. I tend to find autumn a bit depressing, but spring is nice when all the trees are coming into bloom and so on.
