Aachen feels like “Charlemagne's capital, Germany's biggest technical university and two national borders inside a bus ride — a city where 'which country insures me' is an ordinary question”, while Frankfurtis “Germany's most international city — the ECB, the airport, and English that actually gets you through the working day”. Climate is a real differentiator: Aachen — oceanic and noticeably wetter than the rhine valley an hour east — the eifel and the ardennes sit upwind, so aachen catches more rain than cologne, with mild winters and warm rather than hot summers. Frankfurt — oceanic-continental — mild wet winters and warm summers, among the warmer german cities thanks to the rhine-main basin.
