Replying to Whistler, Silverstar or Big white?

So i've got a possibility to go for a working holiday for next season, it would cost 700e for the company to get me a visa, and arrange me a job at the chosen ski resort(+more). I'm yet to be informed on how many hours I would be working weekly and how much I can actually ski besides working. Do you guys think this would be worth it?

Which 1 of these three would have the best park, and the best possibilities for skiing the good stuff when it dumps?

I would apreciate all the answers.
