Do you mean the oceanic climate of France and England, because the ocean moderates the temperatures so winters aren't as cold and summers not as hot as the continental climates in the rest of northern europe.

Speaking as someone who grew up in a continental climate i would not say they're the best. Winters can be horrible and make you it so it's unbearable to be outside for more then 5 minutes.

In general ocean moderated climates are the best because they're much more moderate. Mediterranean climate is the best because of this.
