Softer woods and laminate floors are easy to dent and scratch. Dropping things, Pet nails, things that get under foot, furniture, and even heavy traffic areas can all lead to damaging your beautiful floors. Sure, these can be cheaper to have installed but wear down much faster. Either having to be replaced or refinished which costs more money.
Harder wood floors are much more expensive to have installed but will last much longer. Think of the homes which have had their wood floors 100 plus years. The durability of the wood is much higher. This means its more forgiving with dropped items, pets, and traffic areas. The main reason that they are still hear today is that they had been properly maintained. At least the nice looking ones.
Warning WATER will damage all wood floors if left too long to pool and dry. So when cleaning sweep or use a slightly damp mop.
