In my experience, spray-formed is a nice middle ground between powder steels' propensity for long-term edge retention and razor edges, and traditional steels' toothier carbides, which give more purchase when cutting fibrous materials. PSF27 is basically D2, so it's already tough and easy to handle, and the spray-forming process mostly improves those qualities, making it less prone to chipping. Anecdotally, it's also a little less prone to staining or rust. It's a little harder to work, but if anyone's up to the task, it's Spyderco.
If you're the type to get lost in the woods in midwinter, this is the steel for you. If you just like opening your Amazon boxes with a big, expensive knife, it should be pretty good for that, too.
