Which LEGO Technic set is best for adults who want a display piece?

Among the candidates, the large-scale models such as the Bugatti Chiron 42083 (3,599 pieces) and the Liebherr Crawler Crane LR 13000 are marketed and reviewed as adult display builds. Verified-purchase reviewers rate both highly, though the crane has a smaller review base, so the consensus signal behind it is thinner than the Chiron's.
