Being dead does not make you less great.
Very many good musicians are dead. Some 100s of years.
That’s silly.
Having been a Beatles freak since 1964, it’s always surprised me how little of their solo stuff really works for me.
George:
My Sweet Lord (by far my favorite)
Handle With Care (TW)
Dirty World (TW)
Ringo:
It Don’t Come Easy
No No Song
John:
Starting Over
Gimme Some Truth
Woman
Paul: nada
And in my even more heretical opinion only one post-Fabs album has ever floated my boat (and still does): George’s Wonderwall Music.
One of my favorite John songs…
“Whatever Gets You Through The Night” with Elton John singing harmony and playing piano. I have the 45.
Cool story about the bet Elton made with John about the song.
I like “#9 Dream” also.
I voted John and George. John because of Working Class Hero, Imagine, (Just like) Starting Over, Instant Karma, Whatever Gets You Through the Night, Watching the Wheels, Stand by Me and some more. George because of My Sweet Lord and the Traveling Wilburys period.
But I can’t vote for Paul because all the good-ish stuff he made gets erased by Ebony and Ivory, Mull of Kintyre and similar soppy trash.
Ringo seems to be a wonderful person, but we are talking about music here, right?
^^^John’s cover of “Stand By Me” is another great one.
We like the same music. Cool😊
The whole Rock ‘N’ Roll album is great. Lots of slurring words and other artists. Raw singing. You know they where partying way too much. The Lost Weekend, much?
The first record I bought was a a Beatles 45 with “Revolution.” The A-side had a pretty good song too 
, but that one got a lot of radio and tv play, “Revolution” not so much.
Uh, yeah, but it stops you making music. I meant that Paul has continued much longer and George continued for longer.
Omg. I just pulled Revolution up from my playlist and listened.
Kamala needs to have that as her theme song.
Why don’t they call me about these things?
All Paul ever did was Yesterday.
Literally.
Pretty much what I was going to write. I really dig a lot of John and George stuff, but I love a lot of Paul stuff. He’s also the artist I’ve seen in concert the most time.
Yes!!! 
My favorite version of Stand By Me. Paul’s is weak.
As a teen I wore out my copies of Band on the Run, All Things Must Pass, and Ringo (the 1973 album that contained “Photograph” among other at-the-time hits). Never bought a John Lennon album for some reason, despite seeing “Imagine” as one of the greatest songs of all time.
I honestly couldn’t say which meant most to me. But I guess I’d have to say that Paul has had the best post-Beatles career for both the longevity and the reach of his hits. He has come up with some lovely melodies over the decades.
For me there is no contest - George Harrison. I realize this is subjective - but I like minor key stuff in general. Plus, I think overall he had more, quality songs. Imagine is an amazing song but it is an outlier. Most of John’s post Beatle stuff is crap. A rebelling against years of Paul’s “granny songs”, I’m betting. But mostly I don’t Like post-Beatle John. And I say that as a massive appreciator of John’s Beatle stuff. I believe he was a genius.
For me, too. Off the top of my head, I can’t think of a post-Beatle Paul song that matched his Beatle stuff. And, again, I’m a huge Paul fan (I had 5 row seats to a Wings concert). Though I didn’t like Wings music in general. Apparently, nor did Paul:
“Paul McCartney, a former Beatle, has sometimes criticized Wings’ music, calling the band “terrible” and “not a good group”. In 2016, he said he thought Wings’ first album, Wild Life, was a “blow” and that he couldn’t stand their second album, Red Rose Speedway. ”
Ringo’s output was too marginal to be considered, IMHO.
So in the end, George. I actually think Bangladesh is one the best post-Beatles songs.
If I’d answered this poll 20 years ago, it would have been Paul, easily. Now it’s George, also easily.
As I’ve gotten older, and listened to George’s music more often, he’s become my favorite Beatle, as well as my favorite post-Beatle. Even with a lull in his output in the early '80s, many of his songs are among my very favorites, including a lot from All Things Must Pass, Cloud Nine, and Traveling Wilburys Vol. 1.
Maybe I’m Amazed is such a good song, I can’t believe Paul wrote it. But it’s easily one of the best that any of them came up with, post-Beatles.
Other than that, I can only think of Let Me Roll It, in which he does his best John Lennon imitation.
I gave George the top vote just for that album. Well, that triple album. You get the point.
I’ve gone through phases of liking John or Paul the most. But now that I’m older, I find George’s songs resonate with me the most. It’s purely subjective, of course, but that’s where I’m at and will probably stay.
I hate to hear anyone being dismissive of any of them. I have bought, listened to, and enjoyed albums by all four of them. But if I had to pick just one, it’d be Paul, for the quantity, versatility, and range of his body of work.
Close call between John and Paul for me. I narrowly went with Paul because, even though some of his songs aren’t great (“Wonderful Christmastime”, “Silly Love Songs”, etc.), the ones that are good are some of the best pop music ever recorded (“Maybe I’m Amazed”, “Band on the Run”, “Jet” etc.) and bear repeat listening more than John’s, which tend to be more meaningful lyrically but aren’t really songs you can groove to.
