I saw Clapton in Atlanta in the late 70's. His show was great. He achieved studio quality sound in a huge arena.
He is even older than me, so if you went to his show now...it would have to be with the expectation that it would be subdued compared to his prime.
And there would be a judgement call to make regarding the value...to you.

Side note:
I saw BB king at a 2000 seat arena in the late 80's. I went for one song, Thrill.
Enjoyed the whole show.
