Replying to Skiing vs Snowboarding

Long time snowboarder here, but Ive always loved watching ski videos, and well skiing. In my backyard I set up 1 rail and in the summer was able to learn 270's off the rail. On the other hand, I have been snowboarding for like 10 years now and still struggles to not only land 3's and 5's, but also on rails. I cant seem to spin onto of off rails more than a 180, Ill occasionally land the 270 on a box and 270 off. So basically what Im asking is what do you think is easier to learn tricks on, snowboard or ski's? Ive been toying with the idea to switch lately but I cant really commit to it because Ive invested so much time into snowboards. So what do you guys think?
