I've skied WF twice and Gore once. Gore was about 4-5 years ago in early March, and the conditions were perfect, to include 8-10 inches of fresh snow on second day skiing. All of the mountain was open. From the top of the gondola, you can catch a blue, Foxlair to a green Sunway, or take a short green Ruby Run to a long, blue cruiser named Twister. Both routes get you to the base for a decent long run. If Burnt Ridge is open, Echo is also a nice blue, with roller coaster short steeper drops along the way. But it looks like Gore is now less than half open and the conditions may be marginal. Also, the town of North Creek is small and dull without much variety for eating, etc.
WF is a much bigger mountain. I have not been there in 6-7 years so have not skied the expansion runs. Blues may be a bit steeper, but not by much, and you have more variety. Both Gore and WF are subject to similar weather patterns, so conditions will be pretty much the same. I think WF does a better job of managing trail conditions. And Lake Placid is a great ski town with excellent restaurants and things to do if the skiing is not very good.
