A:Answer https://www.slant.co/versus/18313/18317/~audio-technica-at-lp120-usb_vs_audio-technica-at-lp60
This link will give your the pros and cons of both, but it looks like the main difference is that the lp120 has the ability to make digital copies of records, three speeds compared to the lp60's two, and that the lp120 is a direct drive while the lp60 is belt driven.
