Regardless, they both suck as musicians. They had a few good pieces, but Lennon had more simply because he was more prolific and he launched off a successful band. But if you take a thousand pictures, the best few might compare favorably to an Ansel Adams print, and that's what we see of the Beatles and Lennon. They produced hundreds of songs, and today we know a handful of them well. Some of the rest are ok, and the remainder are junk.
The reason Lennon was successful is not due to his music, but his marketing.
