Replying to 07 seth vs 07 prophet 90

For the past 2 seasons i have been skiing on a pair of motherships (the grey ones without the full height tail) and they have served me great. I just bought and mounted a pair of fritschi freerides on them, and this setup will now be BC only, so i am looking for a new pair of skis to ski inbounds and some slackcountry with.

Basically, i want to ski everything on the mtn, pow, alpine, trees, park, cliffs, booters, etc... I want a ski fat enough for the deep stuff, but good in the park as well. I weigh around 195 and 6'5"

Basically i am mainly considering two skis, the 189cm seth [130/98/118], and the 186cm prophet 90[125-90-113] (also considering prophet 100 but everywhere is sold out)

I can get both of these skis for around the same price, and i was just wondering what people opinions were on the two. (or something else that can be had for around the same price ~450US or 600CAD)

thanks
