Metal or wooden garden trellis, which lasts longer?

Across the reviewers we read, powder-coated or epoxy-coated metal trellises dominate the recommendations for longevity, with verified-purchase reviewers repeatedly citing rustproof finishes and welded construction. Bare or untreated metal (and remesh) is flagged in community threads for rusting quickly, though several gardeners note surface rust is cosmetically unappealing but harmless to plants.
