They're about even I think. Lady Bird's mother-daughter relationship elevates it for me, by far the most interesting thing in both movies (and in EoS the same element is comparatively banal). As for the Academy love, probably helped that LB is less overtly comedic and more melancholy, and has more to chew on thematically (search for self-identity, trying and failing to escape your roots, etc.) Besides, y'know, campaigning.
