When I'm not at school, I don't ski park. I'm with Sholte up there (same mountain), no park there. But when I'm at my boarding school, I ski pretty much only park, because where I go (still west coast) gets pretty bad snow except for a very very certain part of the year...which is when I'm at home skiing the powder. It's fun to ski park, too, sometimes. I learn new tricks/grabs every time I hit up the park, pretty much, since I get about 10 park days in every year at most, so I try to make the most of it.
I'm the exact opposite of you, we get decent snow over here, and I ski natural features/big mountain/bc booters/backcountry lines every time I ski for the most part, with a little bit of park. I appreciate both, and I can see why people would stay in either one. I'm not going to rip on park because hitting a kinked steep rail or a 70 foot jump can be scary shit, you know? When you stomp a trick, though, you feel soooo good. Adrenaline rush for sure.
On the other hand, skiing a steep line can make you literally piss yourself. A nice natural 25 footer cliff with a good landing can basically give you a boner, too. There are nice aspects of both, but to choose which one you want to ski that day it really depends on the conditions of the mountain. I'd rather ski natural stuff 90% of the time, but that 10% of park is also damn fun.
