Both run on local + English at work, so the edge comes down to your sector. Seoul: Technology & electronics, Entertainment & K-culture, Gaming. Sofia: Software & IT services, Business process & shared services, Fintech & payments.
Seoul feels like “Hyper-connected megacity — palaces and street food beside K-pop, all-night cafés and the world's fastest internet”, while Sofiais “Ten per cent flat tax, a 2,290-metre mountain on the city bus route, and a euro that arrived in January 2026”. Climate is a real differentiator: Seoul — continental monsoon — hot humid summers, cold dry winters, four seasons. Sofia — continental at 550 metres in a mountain basin — warm dry summers, real snow in winter, and cold still spells that trap the valley's air for days.
