Bristol has the vertical that Holiday lacks. Rocket and Meteor were a lot more challenging when I was a kid in the 70's but they shaved it off (and widened Meteor) mainly because crowds would gather and tykes like me would scare off the casual crowd and rip it. It's too bad. With todays advanced grooming and snow making the the old steep part at Rocket would be much more manageable. Back then you'd bounce off the tops to avoid ice and rocks.
There's only a few hills in Western New York that could approach 1,000 vertical and Bristol tops that and more. Nearby Hunt Hollow, a private club, has some good vertical and much better steeps. For boarders however I'd imagine that Bristol is pretty awesome. The terrain suits them.
