Replying to Grouse vs Seymour

For some background, I'm going to school in Vancouver and I'm pretty busy, so I'm mostly looking to do some after school night skiing and can't get up to Whistler more than a few times a season. As far as park goes, I mostly ski rails but I like jumping and skiing pipe too, and I'm a good all mountain skier, so the quality of the mountain itself is important for when I can go skiing on the weekends. Which hill builds better/more creative features? I'm not looking for a park with just huge jumps and scary rails, but for well maintained and varied features that they switch around often, and preferably a fat tube rail like COP's legendary lube tube. Thanks
