I switched after almost 10 years of snowboarding, it's just something new to try.
I personally like skiing more, but that's just cuz it's something new to try. A lot of my boarder buddies try skiing every now and then and some of them have switched while some just do it on occasion.
I say give it a shot, but like everyone else is saying, do which ever one you have more fun at, or both if you've got the money/ hookups.
