Hydraulic power steering is technologically more complex, louder, increases fuel consumption and requires more servicing. It has the advantages of more power, less strain on the car's electrical system and better feedback (feeling) when steering.
BMW 5 series has slightly fewer faults. Deffect rate in annual technical inspection is similar for both cars, it's slightly higher for BMW 3 series, so BMW 5 series quality could be a bit better.
