Most people choose a kitchen knife by how it looks, and then wonder why it stops cutting after a month. What matters is not the brand stamped on the blade but the steel underneath it, and steel is always a trade. Harder steel holds an edge far longer, but it is brittle, and a hard blade will chip if you twist it in a squash or drop it on a tile floor. Softer steel forgives all of that, and in return it goes dull faster. Neither one is better. What changes is how often you are willing to sharpen. If you cook every day and enjoy the ritual of a whetstone, take the softer blade and keep it screaming sharp. If you cook twice a week and want to think about it as little as possible, buy the harder one and send it out to be sharpened once a year.
