Is it better to live in Korea or UK?

I'm considering relocating to either Korea or the UK, and I'm torn between the two options. Could you please help me understand the pros and cons of living in each country? I'm interested in factors like cost of living, job opportunities, culture, and climate. I'm also curious about the ease of integrating into each society as a foreigner. Could you provide some insights into these areas and help me make a more informed decision? Thank you for your time and assistance.
