Even after all of the Beatles generation has passed on to the great concert in the sky, the record books will still be around. I can't say I loved all of their work and they were not as great a rock band as the Rolling Stones, but they have some great songs in their catalogue including "Yesterday," "Let it Be," "Eleanor Rigby," "We can work it out", "Help" and more.
While the Stones were more known as rockers, the Beatles did have better ballads and as someone else mentioned used non-standard instruments and not just guitars and drums and piano.
Having lived through it all, it was really an English invasion.
