I think for me it’s Let It Be. I thought the “Naked” version was better for the longest time, but a few years back listening to the original album made me really love it. I think the ballads and slower songs are still better on the Naked version, but the rest sound so full and energetic on the original.
When I first got into the Beatles, I disliked quite a few tracks, all of which I love, or at least appreciate now.
Some of the songs got better with context, some of the songs I just need to be in the right mood for.
On a similar note I loved Let It Be the first 500 or so times I listened to it, but these days I will skip it 9/10 times it comes on.
