Blizzard has been upping their game a lot recently, and love what they are coming out with. Ive heard nothing but great things about their skis. Honestly, out of those choices, I don't think you can go wrong with either ski.
I can share some info about the Devastators as well as a few other people on here. I personally love these skis with all my heart, and pretty much bought those so I could have a daily driver for Snowbird. sI was pretty much in the same position as you, Already have plenty of park skis and needed something to let me have fun all over the mountain.
They're fat enough to where they will get you through just about any type of snow, have the perfect amount of rocker for float, yet still let you lay down carves like a racer. The flex is something I would consider a stiff but playful flex, meaning you have the stability and stiffness to charge, yet you can still whip the tips/tails around for butters without the annoying chattery-ness you see in other softer flex all-mtn skis. they crush landings, even those punchy spring slush ones you'll see up in LCC, and have tons of pop for jumping off of things. Very fast bases if you wax them on the regular, and have probably the coolest topsheets on a ski I have ever seen (Talking about the limited edition graphic, its 10x more bad-ass in person, and its a great conversation starter on the chair when jerries wanna know where you got those dope skis)
very fun pair of skis, 10/10 rating from myself. a few other people will chime in that own them and say the same things, but we cant emphasize it enough. these skis just simply fucking rule .
