Depending on how much broad-brush history you absorb as fact, Kraftwerk invented dance music, whilst the Beatles redefined what pop could be. Kraftwerk gave us the synthesizer and the Beatles brought psychedelia to the masses, Kraftwerk essentially invented synth-pop, and the Beatles popularised the very notion of artists actually writing their own songs.
While the truth is - as with most things in history - a tad more nuanced than that, one thing you can't deny is both bands' indelible influence on pop culture, music, technology, and songwriting.
