Edge retention and corrosion resistance are the two most important traits for any blade. M390 is vastly superior in both respects.
A steel that is easier to sharpen just means more frequent sharpenings. I've never considered that a positive. If I'm breaking out the Wicked Edge to sharpen, M390 might take an extra 15-20 minutes compared to S35VN, but it'll hold that edge much, much longer.
All things considered, for the typical use case of a pocket knife, M390 is objectively better steel. Introducing a new model in 2019 would have been a great chance to upgrade.
M390 won't hold a shaving edge longer than S35VN. It only holds a barely sharp edge for longer. I don't know about you, but I like to keep my knives sharp. So whether or not they will hold a dull edge for longer doesn't make a difference to me. How often do you find yourself battling corrosion on your S35VN? I never have. On the other hand S35VN has better edge stability and chips less than M390. M390 was developed as a steel used for plastic molds, S35VN was developed as a cutlery steel. This isn't a coincidence.
