Our verdict
Reach for a flat trellis like the Amagabeli panel when the job is simply to support a climbing plant against a wall, fence or bed; it is cheaper, easier to anchor and disappears behind the foliage. Choose a walk-through arbor like the Costway arch when you want a structural focal point that frames an entry, gate or path, and you have room for it to stand free. A trellis is a plant support; an arbor is a garden feature that also supports plants. Many gardens use both: trellises along the beds and a single arbor at the entrance. If budget is tight, start with the trellis and add the arbor when you want a statement.
