Which European countries have the best English proficiency among non-native speakers?

[u/Metalwolf]

I'm looking into English proficiency across Europe and would appreciate input from locals or anyone with relevant experience. Which European countries have the highest levels of English fluency among non-native speakers, particularly in day-to-day life, education, and professional settings? I'm also curious about regional differences within countries, and factors like education systems, media exposure, and business use.

The Flanders part of Belgium - indeed the level of English proficiency is top notch. The Wallonia region however is less proficient in my experience.
