PE-cover pop-up vs. polycarbonate panel: which lasts longer?

Across the reviewers we read, PE-cover pop-ups (Ohuhu, Eagle Peak, Greengro) typically need cover replacement after 2–3 seasons of UV exposure, but the frames last much longer. Polycarbonate kits (Garvee, AMERLIFE) hold up structurally for 5+ years per owner reports, but the thin twin-wall panels can yellow and the slots they sit in are a common failure point in wind.
