Which is safer: Koh Samui or Seoul?
Seoul scores higher on safety, 80/100 against 70/100. Safety scores blend crime levels, political stability and healthcare access, and they describe a city as a whole — individual neighbourhoods vary far more than the headline number suggests.

Koh Samui averages 60 Mbps and Seoul averages 216 Mbps, so Seoul has the headroom if you push large files or run video calls all day.
What visa would I need for Koh Samui or Seoul?
Koh Samui sits in Thailand (DTV 5-year) and Seoul in South Korea (90 days). Requirements, income floors and processing times change often, so check the visa and residency guide before you commit to either.
