The official travel site of Finland, VisitFinland, has listed reasons for choosing Finland. The same webpage includes also lists about what to do in Finland at least once, what you won't see in Finland and what you will miss when you leave Finland. You can read the lists here: http://www.visitfinland.com/about-finland/why-come-to-finland/
Welcome to Finland!
