The flexible wire has a small diameter, and the insulation material is unreliable, and it is easily damaged by aging. Even if it is used, it is only suitable for a small amount of use where it is connected to chandeliers and other electrical appliances, and is not suitable for use in fixed long-distance lines.
From the price point of view, since the manufacturing of multi-strand wires is obviously labor-intensive and the cost is naturally high, there is no advantage in price, and single-strand wires are relatively cheap.
In summary, it is obvious that a hard wire is better, but in fact, whether it is a hard wire or a soft wire, it will definitely be used for home decoration. Just remember that a single hard wire is better as the main line.
