Replying to ARV 106 vs. 4frnt Devastator (2020)

Trying to decide between the 2020 Armada ARV 106 and the 2020 4frnt Devastator. Looking for one ski to cover my powder and park days. I've done a lot of slopestyle competition in the past and can ski it all on powder days. Which ski performs best in powder and which ski performs best in the park? And lastly, which would cover powder and park the best?

I'm 6'1" 200lbs, looking at getting the 184 Devastator and 180 ARV106, plan to mount as close to center as possible, may do -1.
