Part of me agrees with you, but for the Eagles I will make an exception.
I’ve never seen them live (and won’t, now that Frey has passed), but with them, I would totally appreciate the meticulousness of their harmonies - vocals and guitars.
Overall, I do enjoy when bands do different things with their tunes live. I love it, actually.
But I feel like I would be in awe of the Eagles duplicating what they did in the studio.
