I searched for an existing thread but either I missed it or there isn't anything recent

IMO the greatest live album ever made is Joe Jackson's Big World, as unless you know the story behind it you'd think it was a perfectly crafted studio album. To my knowledge it is the only major release ever mixed *before* it was recorded.

Next would be Giant's Playing The Fool, aside from the aforementioned BW it may be the least overdubbed/filtered/edited live album ever, and Giant being Giant the arrangements are just sick.

Others (I will add some later, I absolutely cannot list them all from memory here) in no special order

Joni Mitchell - Shadows And Light
Flairck: Live In Amsterdam
Yessongs (needs a SW remix) (also I would love to include the Yesshows version of Gates, my favorite Yes anything, ever)
EL&P: WBMFTTSTNE)
Genesis: Seconds Out
Tull, Bursting Out (with props to the live side of Living In The Past)
King Crimson: there's a lot of them but definitely need to include The Nightwatch
Mike Keneally: Guitar Therapy
Talking Heads: Stop Making Sense
Laurie Anderson: Home Of The Brave (esp. the movie)

Zappa is really hard to discern where live stops and studio starts. He was even known to paste tracks from completely different performances from different shows.

Your turn. For now.
