Appearance and repair
Wood varies board to board and changes color outside. A penetrating finish can preserve a preferred tone but adds recurring work. Composite gives a manufactured palette and repeating surface patterns; inspect several full boards before deciding. Surface damage to a capped product is usually handled differently from damage to solid wood. Ask whether a damaged board can be removed without dismantling a large area.
Maintenance and comfort
Neither option is maintenance-free. Both need debris removal and cleaning. Wood may need finishing to preserve color; composite needs cleaning compatible with its cap. All decking can become hot in sun. Color, exposure and shade can matter as much as the material label. Test full samples in the actual location. Wet traction depends on the product, texture, contamination and cleaning.
Installation and cost
Wood movement is affected by moisture; polymer-containing boards also require temperature-aware details. Joist spacing, diagonal layouts and stair spans must match the selected product. Compare installed scope rather than board price alone: blocking, approved fasteners, fascia, stairs, delivery and waste can change the result. A lower board price does not establish a lower completed project cost.
When each makes sense
Pressure-treated wood suits a restrained initial budget. Cedar or redwood suit a softer natural look. Dense hardwoods suit owners who want real wood and accept specialist installation. Capped composite suits owners who prefer less refinishing and a controlled color selection. Start with those priorities, then check suitability and quotations.
