Newton was more important I think. He basically invented physics as we know it. He didn't have the 200 years or so of work in the field that Einstein had to build on. He was effectively starting from scratch. He's the point at which the modern world starts, when humanity started to understand the world around them instead of letting themselves be subjects of superstition.
