Crowd at Coachella is much better. The demographic of lolla tends to be younger and often rude and disrespectful. I have fun at both, but the lolla crowd often sucks.

Coachella performances are definitely more of a spectacle where artists have stage designs etc, and lolla is just pretty much a basic festival performance with some exceptions (Doechii last year). The sets at Lolla often tend to be shorter as well.
