Both run on local + English at work, so the edge comes down to your sector. Gdansk: Ports & logistics, Shipbuilding & marine engineering, Offshore wind. Lille: Retail & distribution groups, Digital infrastructure & tech, Health & biotech.
Gdansk feels like “A 40-km coastal conurbation of three cities, built on shipyards and now on Baltic offshore wind”, while Lilleis “Brussels in 35 minutes, London in 90, and a rent cap that stops dead at the city boundary”. Climate is a real differentiator: Gdansk — baltic maritime — milder winters than inland poland but relentlessly grey and windy from october, with barely seven hours of daylight at the solstice and a short brilliant summer. Lille — cool, grey and damp — a long heating season, few genuinely hot days, and rain in every month.
