Generally agree with you, but I have a few selective exceptions and one of my main ones are the 1994 Pink Floyd concert where they - in the video version - bring out the mother of all disco balls during Comfortably Numb

It's a 10 minute long performance and literally half of the time is the guitar crying in beautiful agony. Just go to the 5 minute mark if you want to hear one of the best guitar solos ever made. And this comes from someone who isn't really a fan of long guitar solos.

Another live performance that I prefer over the studio recording is Runrig's Only the Brave. It just feels appropriate that it's a big crowd for this specific song. It feels like a song that should have a whole stadium of drunk, happy Scotsman singing along. It always brings a teary smile to my face, when I listen to this live recording.
