Cobra is softer than the phoenix. I bought the phoenix a year used at a steal. It's gonna be my early/late season shit snow icy groomer board. I have a heritage for sale.. I wanted something a little more playful and a little better in pow... hence the cobra. The cobra is gonna be my good snow mid season board. Heritage is up for sale as it no longer fits in my quiver.
If your only going to have one board go with the cobra.
